INTRAVIA’S SERVICE GUIDE TO COPIERS
EDITIONS 1, 2, 3, 4, 5, 6 , 7, 8, 9
90% of all dry plain paper copiers manufactured from 1975-2001 are covered. The first two have been combined into one, making a total of six books. Every few years a new book comes out, covering the next group of machines. The books fit in your tool case. Information includes diagnostics, trouble codes, simulations, PM items, copy quality adjustments, developer calibration, reset codes. All machines are listed by manufacturer with complete cross references. Designed for experienced copier technicians. They are not training manuals.
These are the manuals that you most often hear about. Quite frankly, these particular books are, I feel, my most important contribution to the copier service industry. Every technician who works on copiers should have them. Virtually every dry plain paper copier ever made, below 50 copies per minute, is covered in. It is impossible for you to purchase a factory service manual for every machine. I do this for you, and then present you with the most essential information. There are no disassembly instructions, or detailed troubleshooting steps in these books. I assume that you are a qualified and competent technician, who needs information. That is what I supply. Typically, several similar machines from each manufacturer are grouped. All the information you need to troubleshoot and PM the machines is included. In the front of the 7th edition is a very accurate cross reference, which also tells you which edition a particular machine is located in.
Here is a partial sample from the 7th edition.
PROFILE
Speed: 1120 is 20 copies per minute. 1212 is 12 copiers per minute.
Toner: 947-122 Stated yield: 7500 copies. Likely yield: 4,000 copies.
Developer: 947-123 Yield: 30,000 copies.
Drum: 947-124 Yield 60,000 copies
Full PM: 30K
Fuser cleaner roller: 947-124. Yield: 30K
Waste toner is recycled.
Developer Calibration: After changing developer, enter "47" mode. Enter output 51. Press "Print". Display will flash and machine will cycle for about 1.5 minutes. If this is not done, machine will often (maybe always) go into a code 26 and will not operate.
Copy quality adjustment: Turn off power. Hold down "3" and "6" keys while turning on power. Press "9". Press "0". Make test copy. Press "P". Note reading and enter new value (higher will be lighter; range is 1-64). Press "P". Make test copy. If good now, shut power to lock in. If more adjustment is needed, repeat procedure.
Auto exposure adjustment (AES): Put test chart on glass. Shut power. Hold "4" and "7" keys while turning on power. Press "9". Press "8". Press "print". "98" will flash in the display. When it stops flashing and lights steadily, AES adjustment is complete.
Registration adjustment: Turn off power. Hold down "3" and "6" keys while turning on power. Press "9". Press "1". Press "P". Note reading. Enter new value. Press "P". Press print to make a test copy. If OK, shut power to lock in. If not, repeat procedure to adjust further. Range is (-)10 to (+)10.
PM reset: Hold "4" and "7" down while turning on power. Enter "9", "0". Press "Print".
Reading PM count (Copies since last PM). Hold "P" down and simultaneously press "5".
Clearing PM count. Simulation 47-90. Shut power. Press "4" and "7" and hold down while turning on power. Then press "9", then "0". Then press "Print".
Reading total count: Hold "P" and press "1".
DIAGNOSTICS AND SIMULATIONS
TROUBLE CODES
J11 Feed jam.
J12 Feed jam.
J13 Feed jam.
J14 Jam inside.
J72 Sorter jam.
F09 Power leakage of some kind. Heat, exposure, AC or power supply or main relay. Go to "25 mode" and select "P49" and reset to "0".
F23 Toner motor.
F26 Toner density adjustment problem.
This means the machine is undertoned. To repair, replace developer and enter "47" mode.
Press 51. Press Print. Allow the machine to cycle until it stops. Some feel you should
disconnect the toner motor first. This code happens probably because either the machine
wasn't set up properly, or because the customer kept using the machine with the toner light on.
TROUBLE CODES - continued
F28 Corona problem. Could be any corona.
F34 High fuser temperature.*
F35 Low fuser temperature.*

P27 Toner density sensor ulnplugged or toner density sensor problem.
P64 ADF & operator are confused.
Remove original.
P68 ADF feed problem.
P69 ADF feed problem.

*Note: To reset F34, F35, F36; enter the"25 mode". "P47" and reset to "0".
"25 Mode": To enter this mode, turn off power. Press the "2" and "5" keys and hold them down. While they are held down, turn on power. You will now use the number keys to select the code that you want. Press the "P" key.
04: PTC heater. Don't know what this is, but 0 means it is not installed. 1 means it is.
P11: Count. For total count, select "0". For developer count), select "5".
P12: Preheat mode fuser temperature.. 0 for 356 degrees. 1 for 374 degrees. 2 for 383 degrees.
P15: Size priority. 0 is standard. 1 is a size priority.
P16: Paper size priority. 0 for 11 X 17. 1 for 8 1/2 X 14. 2 for 8 1/2 X 11. 3 for 8 1/2 X 11R. 4 for 5 1/2 X 8 1/2. 5 for special. 6, 7, 8 are all for 8 1/2 X 11.
P19: Preheat shut off timing. 0 for 1 hour. 1 for 2 hours. 2 for 3 hours.
P22-24: Kind of obscure. This sets the wait time for tuning intermittent test copies in a 36 mode test. P24 is for the 1st digit. P23 is for the 2nd digit. P23 is for the 3rd digit. Can be set to any digit (seconds) from 1-250.
P26: ADF border erase. 0 for none. 5 for 5mm.
P27-28: PM cycle. 27 is for the 5th digit. 28 is for the 4th digit. In other words (I hope!), if you wanted to set a PM cycle of 26,000 copies, you would set 27 to "6" and 28 to "2". If you wanted 9,000, you would set 27 to 0 and 28 to 9.
P32-37: PM count. To reset the PM count to 0, you would set each of these to 0. To set it to some other number would probably make you nuts, but here is how. 32 is for the 5th digit (tens of thousands), 33 is 4th, 34 is 3rd, 35 is 2nd, 36 is 1st, 37 is ones. So for example if you wanted to make it look like the machine had run 145891 copies since the PM, you would set 32 to 1, 33 to 4, 34 to 5, 35 to 8, 36 to 9 and 37 to 1. If you wanted to clear the PM count (reset to 000000), just use simulation 90 in the "47 mode", which is explained elsewhere.
P39-44: Drum count. Use same procedure and rules as P32-37.
P45: After a high voltage (corona problem), clear the F09 code by setting this to 0.
P46: Sorter priority. 0 for non-sort mode. 1 for sort. 2 for group.
"25" Mode - continued
P47: Fuser code reset. Set to 0 to clear fuser trouble codes.
P48: Auto reset after run is complete. If 0, will not reset. If set to 1, will reset after 2 minutes.
P49: Reset trouble code F09: Set to 0 to reset.
P50: 11 X 17 double count if set to 1. Will count 11 X 17 as one copy only if set to 0.
P53: Auto tray selection if set to 1. None if set to 0.
P56: When using ADF, the machine can be set to any of several modes.
P57: If key counter connected and set to 0, and key counter is removed, copy will exit and then machine will stop. If set to 1, machine will stop immediately when counter is removed, even in mid cycle.
P58: At power up, machine will default to ADF, APS and/or AES, depending on which is selected.
0 all 3.
1 APS and AES.
2 ADF and AES.
3 AES only.
4 ADF and APS.
5 APS only.
6 ADF only.
7 None.
P60: Bias shift. 0 for -150 volts (standard). 1 for -180. 2 for -200. 3 for -130. P61: Original mix. If set to 0, all originals must be of the same size. If set to 1, originals of different lengths (lead edge to trail edge) can be sent through the ADF.
P61: ADF mixed original mode selection if set to 1.
P62: Auto shut off timing after a run. 0 is none. 1 is 2 minutes. 2 is 5 minutes. 3 is 10 minutes.
P64-69: For total count. Use the same procedures as for P32-37.
P70: Margin elimination. 0 is all modes. 1 is APS/AMS. 2 is all modes. 3 is ADF/platen, APS/AMS.
P81: Internal heater on if 1 (installed.) Not if 0.
P83: Size selection/casette selection switching. 0 is size. 1 is cassette.
P85-90: Developer count. Use the same procedures as for P32-37.
P91: Paper feed unit option. 0 if not installed. 1 if one PFU is installed. 2 if two PFUs are installed. 3 if 3 PFUs are installed.
P92: Add toner choice. If you want the machine to stop operating completely if the customer runs 300 copies after the Toner light comes on, set to 0. If you want to let the dummies run forever without putting in toner, set it to 1.
"36 Mode". Turn off power. Hold down the "3" and "6" keys while turning on power. "CC" will light in the display. Use the number keys to enter your code. Press "Print". "01" will display. Press "P" and hold it. While holding "P" use the number keys to enter the code number. The existing setting will show in the display. Enter your new value with the number keys. Press "P". Enter a number of copies that you want to run. Press "Print" to test the machine to see if you got what you wanted. If not right, repeat the procedure. If all OK, shut power off to lock in your new settings. If you need to switch something from (+) to (-) or (-) to (+), press the "Stop/Clear" key.

"47 Mode": To enter this mode, turn off power. Then, press "4" and "7".
While holding them down, turn on power. You will be checking "Inputs and Outputs". Inputs
are signals that go to the main board; such as paper path sensors, toner sensor, scan switches
etc. Outputs are signals from the main board that operate items, such as toner motor, exposure
lamp etc. In the case of Inputs, the state of the switch or sensor, will give a "H" or "L"
indication on the display. When you actuate, move, trip or otherwise activate the device, this
state should switch, if it is working. In the case of outputs, you will press the "print"
button to test the particular item.
After entering the "47 mode", select the item with the number keys. Then do your test. In
many cases, inputs and outputs have the same code. To test an input, after you enter the code,
actuate the item and check the display, or in some cases the display will be active
immediately. Once you press the "print" button, you will be testing an output. Press
"stop/clear" to end an output test. Turn off power to exit the mode.
