Canon Imagepress C1

[irtek]

I have an IPR C1 I am servicing that has a cq problem. A little background. This is the only one I have worked on. It was bought from a wholesaler used with about 85k on it. At 90k the magenta started washing out on it, so I did a dev stir and Auto Gradation and the density came back, but I noticed the magenta solid on the Auto Gradation print had pits in it. They were not very noticable looking directly at the print but it you looked at an angle you could see it easily. The other colors were fine. So I change the magenta dev. and problem solved. Now 2 months later with 109k on the machine the cyan started washing out and now cyan is very pitted and yellow and black are also pitted but not as much as the cyan. Also the magenta is also starting to pit but very little. I'm pretty sure changing the developer will solve the problem but is this a common problem on this model? Is there something I can do to keep this from happening? This is the only IPR C1 I have worked on but I have a lot of experince on CLC 1000 and IRC 3200 and have never seen this before. Thanks for any help on this.

Remove the ITB assembly and inspect the belt for small pit marks. If pit marks are found replace the belt. The pit marks are causing arching from the transfer roller to the belt.

First _ get a Manual
second/_ update firmware
third/ how old is Drum/ and in what condition

Pitted/ do u mean grainy a feel ???

When Ring Marks or Dots appear on output images, follow the procedure described below after replacing
the Start Developers or the Developer Assemblies.

1. Pull out the P-Kit.
2. Remove the ATR Stay [A].
3. Remove the Backing from the Two-Sided Tape on the ATR Stay Sheet [B], and then put the Sheet onto
the ATR Stay [A]. Do not remove the solenoid [C] because the position of the Solenoid was adjusted.
When applying the ATR Stay [B]. The ATR Stay Sheet will be set up as a new Service Part.

When attaching the ATR Stay Sheet [B], align the edge of the Two-sided Tape on the ATR Stay Sheet to
the edge of the ATR Stay .

Many factors play a roll in Foreign Objects entering the Developer Assemblies, this Countermeasure will
not cover all cases; therefore care should be taken to make sure the Developer Assemblies are paced on a
clean surface when working with them.

P-Kit Assembly=FM2-2528-010

Sheet, ATR Cross member=FC6-1362-000

My Opinion/Get rid of those crappy dev units

[SCREWTAPE]

Most in deed replace the transfer belt if it hasn't been replaced. Its good for about 70K.
I change developer at 60K at times. Even though the service guide states the life is 500k.
Firmware definitely should be considered.

Thanks for the replies. The transfer belt did have pit marks on it when I first checked it out at 85k. I replaced the transfer belt and transfer roller. This problem is not ring marks or dots I have seen that on CLC 1000. It looks like tiny craters in the solids. They are not deep enough to show the white paper so they are hard to see looking directly at the print, but easily seen at an angle. The problem is developer specific because the first time it was only the magenta and replacing the magenta developer fixed the problem. I have a manual, I will check the firmware version, I do not know how old the drum is but it looked in great condition.

I have SST 4.11 can someone please help with the software? Thanks.

4.11 will do the trick for you, but having the latest is always a good idea...

Another thing I found to look out for if you have those marks on the transfer belt is a foam roller in the duplex area under the fixing feed unit, it can distintigrate and leave bits of rubber on the pages when dupexing which will end up on the belt -

as far as the developing units - just order new ones dont bother reloading starter!

good luck
