3. drive mechanism the document is fed into the scanner by the scanner roller [a], and fed out by the exit roller [b]. the tx motor [c] drives the scanner roller and the exit roller. the document exit sensor detects when the document leaves the scanner. note: when a communication error occurrs in immediate tx, the machine stops scanning the document, then feeds it out of the scanner. [a] [c] [b] h528d512.wmf [d] h528d513.wmf detailed section descriptions july 30th, 1996 scanner 2-2
4. image scanning the scanner consists of a contact image sensor (cis) assembly [a] and a scanner roller [b]. inside the cis are an exposure glass [c], a rod lens array [d], an image sensor [e], and an led array [f]. the image sensor consists of a row of 1728 photosensitive elements (216 mm width x 8 dots/mm). light from the led array is reflected from the docu- ment and focused onto the image sensor by the rod lens array. because of the short optical path inside the cis, the focal depth is much shorter than for a ccd type scanner. the white level adjustment is performed at the factory, then the white level is stored in the fcus sram. the white level must be adjusted when the fcu or the cis is replaced, or the sram is cleared in the field. the cis scans the document one line at a time, and outputs an analog signal for each line. the voltage from each element depends on the intensity of the light reflected by the document onto the element; the intensity of the light de- pends on the darkness of the area reflected. cross reference white level adjustment: service tables and procedures (chapter 4) - function 10, shading test [a] [b] [c] [d] [e] [f] h528d515.wmf july 30th, 1996 detailed section descriptions scanner 2-3

2.2. printing 2.2.1. printing process - overview this machine uses a "write to black" system, using negative toner. the charge brush roller applies a negative charge to the drum of -350 v to -1350 v, switched at 30 hz. the surface voltage of the drum is approximately -800 v. the laser exposed area on the drum drops to about -50 v. the development roller carries toner to the latent image on the drum surface. the bias voltages during printing: development roller : -300 v doctor blade: -550v lower case: -287 v the transfer roller attracts toner from the drum onto the paper. the bias applied is +3.2 kv. this machine has no cleaning unit or waste toner tank. h528d545.wmf detailed section descriptions june 30th, 1996 printing 2-7
2.2.2. opc drum this machine uses an organic photoconductor drum [a]. the diameter of the drum is 30 mm. it is driven by the main motor [b] through a gear train [c]. the charge brush roller [d] is also driven by the main motor. the drum cartridge is replaceable by the user. 2.2.3. charge the charge brush roller [a] is located in the drum unit. it applies the charge bias in direct contact with the drum [b]. the high voltage power supply applies a high voltage of -350 v to -1350 v, switched at 30 hz, through plate [c]. since the machine uses a charge brush roller, the ozone production is greatly reduced and the charge bias applied to a roller is relatively low compared to that for a corona wire. the charge brush roller rotates faster than the drum. (the speed ratio is about 4 : 1.) there is no cleaning mechanism. also, toner is transferred back to the drum by the transfer roller in cleaning mode. the charge brush roller picks up some of this toner. in extreme cases, this may lead to vertical black lines on copies in areas corresponding to places on the brush that have excessive toner.

2.2.4. laser exposure 1. overview the components of the laser section create a latent image on the drum. the charge on the exposed areas of the drum drops to about -50 v while non-exposed areas remain at about -800 v. this machine uses a rotating square mirror [a]. the beam emitted from the lddr [b] is reflected by the square mirror to the line synchronization detector [c] for line synchronization in the main scan direction. the mirrors rotation speed is 8431.7 rpm. as a safety feature, the shutter [d] closes to block the laser beam path whenever the top cover is opened. cross reference group 3 facsimile manual: section 4-3-3 2. error conditions ld failure : the mechanical control board detects an ld failure when the laser power is out of the specified range. when this occurs, the machine warns the user on the lcd panel (sc code 2-22). [c] [b] [a] [d] h528d505.wmf detailed section descriptions june 30th, 1996 printing 2-9
mirror motor failure: the machine detects a mirror motor error when the mcb does not detect the line synchronization detector signal within 1 second of the mirror motor being turned on. the machine also detects a mirror motor error when the motor rotation is not within 8431.7 rpm 5% at 4.2 seconds after the motor turns on or if the motor is not within 8431.7 rpm 3% for more than 0.5 second during mirror motor operation. since this error is detected with the line synchronization detector signal, the machine may detect ld malfunction as a mirror motor failure. when these errors occur, the machine warns the user on the lcd panel (sc code 3-31). cross reference service call conditions: section 7-3 3. toner saving mode in this machine, toner saving is done by reducing the number of dots actually printed, not by varying the development bias. in toner saving mode, the image data is filtered through the following four-line matrix. 1st line 1 0 1 0 1 0 1 0 1 0 . . . . . 2nd line 0 0 0 0 0 0 0 0 0 0 . . . . . 3rd line 0 1 0 1 0 1 0 1 0 1 . . . . . 4th line 0 0 0 0 0 0 0 0 0 0 . . . . . (1: actual data printed, black or white; 0: always a white pixel) note: toner saving mode only works when printing fax messages and re- ports. (however, toner saving is disabled when receiving a half- tone mode message in nsf/nss mode.) when toner saving mode is selected, the print image density is automatically set to "normal"; in some cases, the image may be- come invisible if the lighter setting is used. cross reference toner saving mode: user parameter 12, bit 2 edge enhancement in toner saving mode, the machine prints a black pixel whenever the data changes from white to black in the main scan direction. in this way, edges on the image are printed more clearly. july 30th, 1996 detailed section descriptions printing 2-10
2.2.5. development 1. overview this machine contains a development toner magazine (dtm) [a], which contains the toner agitator [b], development roller [c], toner supply roller [d], doctor blade [e], and the toner tank [f]. at toner end, the entire dtm is replaced by the user. there are two rollers in the dtm: the toner application roller [d] and the development roller [c]. the toner agitator [b] stirs the toner and carries it to the toner supply roller [d]. the toner is then carried from the toner supply roller to the development roller. as the development roller turns past the doctor blade [e], only a thin coating of negatively charged toner particles stay adhered. cross reference group 3 facsimile manual: section 4-4-2 during printing, a bias voltage of -280 v is applied to the development roller (when a print density setting of normal is selected). the development bias changes in accordance with the print density selection (user parameter 12, bit 3 and 4). since the laser exposed areas on the drum are reduced to -50 v, the toner is trasnferred from the development roller onto these areas of the latent image as they turn past the drum. there is no dtm detection in this machine.

3. toner end detection the toner end sensor [a] (a reflective photosensor) is located under the dtm. when the toner is almost empty, the sensors light is reflected by the mirror [b] at the top of the toner tank. the machine monitors this sensor only when the main motor is on. if the sensor detects the reflected light 5 times in a row, within a specified period, the mcb detects a toner near end condition, and informs the fcu. the machine can then print 100 more sheets, at which time the fcu disables printing (toner end condition). at this time the dtm must be replaced. 2.2.6. paper feed 1. paper path [a] [b] h528d508.wmf [a]: paper pick-up roller [b]: paper feed unit pick-up roller [c]: registration sensor [d]: paper exit sensor [e]: paper end sensor [f]: standard tray [g]: optional paper feed unit [a] [b] [c] [d] [f] [g] [e] h528d547.wmf detailed section descriptions june 30th, 1996 printing 2-13
2. paper feed mechanism (standard tray) paper feed sequence when the paper pick-up solenoid [b] is turned on, the motor rotation is transferred to the paper pick-up roller [c] by the spring clutch [d]. when the solenoid is turned on, it allows the tray lifting cam [e] to rotate. this allows the bottom plate [f] to be pushed up by the spring. the top sheet of paper in the tray is fed by the paper pick-up roller. the paper feed solenoid is then turned off. the separation pad [g] prevents multi-feeding. the paper activates the registration sensor [h]. this sensor warns the printer that a sheet of paper is coming, to initialize the laser engine. it is also used for paper size and jam detection. if the paper size is determined not to match the selected paper size, a paper size error is detected. the machine stops printing and indicates the user of the incorrect paper size, but the image data is retained and will be printed out when the paper is reset in the tray. when the solenoid is turned off, the paper feed roller stops and the bottom plate returns to the original position. the paper end feeler [i] drops into the slot in the bottom plate to detect paper end when the paper tray is empty.

2. cleaning mode if the paper is smaller than the printed image, or if a paper jam occurs during printing, toner may be transferred to the the transfer roller surface. to prevent toner from transferring to the back side of copies, the transfer roller has to be cleaned before the next printing run. while the machine is in the cleaning mode, the charge is applied to the drum, the drum is completely exposed by the laser, and -800 v is applied to the transfer roller. the negatively charged toner on the transfer roller is then transferred back to the drum. during the cleaning mode, the positive bias of +100 v is applied to the development roller to avoid any toner transfer to the drum. the machine goes through the cleaning mode in the following conditions: at power-up when the printer cover is opened and then closed during printing. after a printer jam has been cleared. detailed section descriptions june 30th, 1996 printing 2-17
2.2.8. fusing 1. fusing temperature control the power supplied to the lamp [a] is controlled by the mcb. the mcb uses the thermistor [b] to determine when to turn the fusing lamp on and off. when the main switch is turned on, the machine turns on the fusing lamp and raises the fusing temperature to 181 c. for printing, the machine keeps the fusing temperature at 176 c. when the printing operation is finished, the machine keeps the fusing temperature at 161 c for 3 minutes (depending on the power saver mode settings). points to note: printing temperature: 176 c thermistor maximum: 250 c thermostat maximum: 180 c (the temperature of the hot roller would be about 300 c. 2. power saver mode settings the behaviour of the machine after printing depends on the following: user level power saver mode setting (100 c or room temperature) power saver mode timer (system bit switch 0b, bits 2 and 3) - user setting: fusing lamp on (100 c) - after printing, the fusing lamp temperature drops to 161 c. then, the fusing lamp temperature will fall back to 100 c after 3 minutes, regardless of the system bit switch setting.

4. fusing unit service call conditions the machine warns the customer on the lcd panel (sc code 0-02) when any of the following conditions occur (error code 9-22). when the fusing temperature is below 90 c and does not increase at least 20 c within 12 to 30 seconds after the lamp turns on. if the fusing temperature does not exceed 157 c within 60 seconds after the lamp turns on. if the fusing temperature drops below 70 c when the low temperature (100 c) is selected in the power saver mode. if the fusing temperature drops below 145 c while printing. if the fusing temperature exceeds 200 c for more than 50 ms. cross reference service call conditions: section 7.3 power saver mode: section 2.3.1 5. fusing unit fan the fusing unit fan cools the machine. the fan motor turns on for 2 seconds when the machine is turned on. it also turns on during printing and turns off 3 seconds after printing. the mcb detects a fusing unit fan error when the voltage of the motor falls below 160 mv for more than 2 seconds while turning. detailed section descriptions june 30th, 1996 printing 2-21
2.2.9. page separation and data reduction incoming pages that are only slightly longer than the copy paper may be reduced in the sub-scan direction. whether or not this happens depends on the settings of printer bit switches 03, 04 and 05. reduction enabled if bit 0 of printer switch 03 is at 1 (enabled), the data will be reduced in the page memory to fit on the paper. however, data will only be reduced if the length of the incoming page is between 5 mm shorter and a certain maximum length. this maximum incoming page length that can be reduced depends on the copy paper size and on the reduction ratio stored in printer switches 04 and 05. each paper size can be programmed with a separate reduction ratio. in each of the two bit switches, there is one bit for each possible paper size. the combination of the bit settings determines the ratio for that paper size. bit no. switch no. bit 7 bit 6 bit 5 bit 4 bit 3 bit 2 bit 1 bit 0 not used not used legal f, f4 a4 letter not used not used sw 04 0: 4/3 1: 4/3 0: 8/7 1: 12/11 0: 0: 1: 1: sw 05 the following table shows the maximum incoming page length that can be reduced for each paper size. all lengths are in millimeters. the factory setting of the reduction ratio is 4/3. copy paper type copy paper length maximum reducible incoming page length. ratio = 4/3 ratio = 8/7 ratio= 12/11 a4 297 386.0 330.9 315.8 f/f4 330.2 411.7 368.8 352.2 letter 279.4 362.6 310.6 296.6 legal 355.6 411.7 397.9 379.7 note: the page memory cannot reduce incoming pages longer than 411.7 mm. incoming pages that are longer than the maximum length will not be reduced, but will be printed on two pages and treated in accordance with the setting of bit 1 of printer switch 00. if this bit is 1, the bottom few lines of the page will continue from where the first page left off. july 30th, 1996 detailed section descriptions printing 2-22
reduction disabled if bit 0 of printer switch 03 is at 0 (disabled), the data will not be reduced. however, if the incoming page is up to x mm longer than the copy paper, the excess portion will not printed. the value of x can be from 0 to 15 mm. it is determined by the setting of bits 4 to 7 of printer switch 03. hex value value of x 00 01 and so on until f15 messages more than x mm longer than the copy paper will be printed out on two pages in accordance with the setting of bit 1 of printer switch 00 as explained earlier. 2.2.10. paper size selection if the machine has an optional paper feed unit installed, the paper size to use is decided in accordance with the following rules. if both trays contain the same paper size, the machine uses the paper in the optional paper feed unit first. if the received page has to be split up and printed on two pages, both pages will be the same size. if the trays contain different sizes, the paper size chosen for printing the received fax message is selected in accordance with the following table of priorities. the table assumes that reduction is enabled and that the reduction ratio is 4/3. received fax message size selected paper size letter a4 f, f4 legal letter 1 2 3 4 a4 4(r) 1 2 3 f, f4 4(r) 3(r) 1 2 legal 4(r) 3(r) 2(r) 1 the paper size priority is graded from 1 to 4. r: the data is reduced to fit on the printer paper. detailed section descriptions june 30th, 1996 printing 2-23
