[Error Code] IR C6800CN Black stripes: E000747-2028 , E000747-0331, E000020-0190

[manya]

Canon IR C6800CN, prints evenly closely spaced black stripes in the direction the paper exits the printer (1mm black/white stripes horizontal to long side of A4 paper / stripes vertical to short side of A4 paper). The prints are the same whether there is a paper on the copier glass or there isn't a paper placed on the glass, same applies when trying to print using the network connection. The following errors E000747-2028 , E000747-0331, E000020-0190 are generated intermittently and the main power needs to be cycled. I have performed a drum phase adjustment in service mode as it was requesting "Check Drum Phase", prior to adjusting drum phase copies were blurred with black/white stripes, now copies have only black stripes. When performing test print MCYBk Horizontal Stripes (TYPE=10) using service mode in colour, print outs have Red, Blue, Yellow, Black (12mm stripes horizontal to long side of A4 paper / stripes vertical to short side of A4 paper) and grainy with all colours having a tint of black. When test print - 16-Gradation (TYPE=4) image is overlapped with black stripes. The pressure roller seems to be wearing out as I found a lot of red silicon shavings which I cleaned, the shaving seem to be from one end of the lower pressure roller and the unit housing the fuser gets very hot, compared to when it was in the UK. Currently looking to source new pressure roller and fixing roller. The machine is currently in Sri Lanka, not sure if there needs to be temperature adjustments (humidity switch, etc). The A-Si drum has completed just over 250000 copies and the service manual states it has a life of 500000. Please advise if there is more to it than replacing fuser parts which I am looking to source. Please advise where the problem could be. Local Canon dealer in Sri Lanka is not interested, as they didn't sell the machine. I have no problem taking it apart as I have cleaned the primary charging wires in the past.

Clean the connector strips of the sub boards(horizontal) in the main controller cage with fine sandpaper and alcohol and re-install them. Reseat connectors on Main Controller and DC Controller.

Thank you will try what you suggested

Bad Memory

Teckat, can you please advise what you mean by bad memory (SODIMM, DDR) and how I can fix this.

Also check your
PRIMARY CORONA ASSEMBLY
for ARCHING

[teckat]

Make sure your Firmware is at v16.03a- it addresses some xtra E747 issues

Board cleaning/ and positions check for E747 Issues

Clean the terminals (both front and back) of the Sub PCB using a lint-free cloth, lightly impregnated with alcohol. Be sure not to damage any of the terminals. If damage occurs, replace the Sub PCB in Question.

After the alcohol has dried completely, hold the Sub PCB firmly and slowly insert it approximately halfway.
You can see this by looking at the mounting holes of the PCB. The mounting holes will be to the
left of the cage frame.
BD2.JPG
After the PCB is mounted half-way, place the mounting screws loosely in place (approximately 1mm between screw and frame).
BD3.JPG
Measure between Sub PCB’s. As each PCI slot is lined up, the measurement from one Sub PCB to the next should be equal.
BD4.JPG
When measuring, do not use the upper PCB of the PDRM-EF-A PCB assembly.
Measure the lower PCB as it is connected to the PCI slot.
If all Sub PCB’s are equally distanced, press the Sub PCB into a full mounted position, and then tighten the screw nearest you first.

Then tighten the screw nearest the frame second.
BD6.JPG
Re-measure and confirm the distance from one Sub PCB to the next.
Once confirmed, re-assemble the Main Controller Cage Assembly Cover and Rear Cover.

Teckat, thank you for the brilliant description, will do this. How can I check the firmware and update it if necessary to v16.03a. I understand I will need a Canon Service Support Tool to perform a firmware update, which I don't have. Do you know where I can purchase the firmware and update tool or where I can download it from?

Thanks for all the advice, I have tried everything suggested but still the same problem as in the previously attached pictures.
Found red shavings in the fixing unit, from the lower pressure roller and upper fixing roller.
I think these need replacing. I think the machine is getting too hot and requires an air conditioned
room as it is located in Sri Lanka and there is quite high humidity, as the plastic vents on the left
of the machine has turned slightly brown since shipping it their from the United Kingdom.
The machine worked for about a month, since being shipped over.

If there is anyone in Sri Lanka who can fix this machine please contact me.

Do you have the exact voltage and cycle (Hz) as the UK.

Clean or replace your filters, when brown or magenta residue is on the vents.

The a.c. mains voltage in sri lanka is between 230V and 240V and has a frequency of 50Hz.
Nominally 230V, with some minor fluctuations, this is the same as the U.K.

Re: IR C6800CN Black stripes: E000747-2028 , E000747-0331, E000020-0190

yes your fuser needs rebuilding and yes this machine should be ran in a controlled environment. The heat and humidity will ruin the toner and starter while it is still in the developer units rendering the machine useless.

Your 747 error codes are a communication issue which could be a build up of corrosion, loose connector or possibly a bad board all together.

As for the digital lines you posted I would look at your replacing your RAM as teckat mentioned and replacing the Main Controller-Sub pcb FM2-5899-000

u posted on this issue last January/February of 2011 ---???
where have u or this printer been since then ?

where I posted some issues for u to look at

did u replace the memory-

020-0190=YELLOW ISSUE///check patch image read sensor--check ITB Sheet

If the process unit is left alone for a long time in a high humidity environment, the primary transfer ATVC control mechanism that goes on when the main power is turned on can cause electrical discharge between the primary transfer roller and the primary transfer static eliminator. The discharge can cause the resistance of the primary transfer roller to fluctuate. Malfunction of the primary transfer ATVC control mechanism can lead to an error associated with E020 or can adversely affect color reproduction.

check in service mode below
