Canon IR105+ grey background....please help me!

[tinnyjay]

I have a problem with my Canon IR105+ at my copyshop.
All the copies i make are the same,all grey.
I tried to open DADF and to make a black copy,but still the same thing,its not black one but a grey copy.
Here you can see the problem

Have you tried printing out test pages. A PG4 would be a good test page. This would help eliminate the machine to see if there is a problem with your high voltage transformer(HVT) or Pre-exposure,or corona ass'y.

Is this happening off the glass??

If so, try doing a CCD adjust in service mode with about ten sheets of the brightest paper you have covering the copy glass or with the DADF down.
Also, is the lamp coming on. If you try doing the CCD adjust and it fails,
your lamp could be going bad or your CCD could be going bad.

I dont think is a scanner problem because also in printing i see the same problem.
Somebody said me to clean Developer Assambly or Corona(s).

There is no edge voids. There is poor contact for drum ground or developer bias. Or possibly wrong toner, but that just doesn't look like wrong toner to me.
Check the red cable for developer bias, its easy to get that connector seated between the plastic insulation and connector. Check that the bias tab (A) isn't too far forward, it can actually arc or touch the drum and get grounded out.

It could also be potential control. To test, set copier>option>body>po-cnt to "0". I had one on which the two pin connector on the potential control board was loose.

I did like you say but still no diference!!!

did you feed lef or sef? if sef, it looks to me, that there is a blank area at the start of the page, which would rule out the charging corona as a faulty part. Stop the maschine while doing prints by opening the front door, have a look at the drum, what did it look like? Are you really sure, that the toner is the right one? What about the Drum cleaning assy? looks for me, as if the waste toner is not properly removed from the drum. Are the erasing leds plugged in and ok?

Try replacing your Pre-transfer and primary corona ass'y rather than cleaning them.
Also check pre-exposure lamps to see if there coming on. Or as I said your HVT.

try this old tech trick>
place a piece of electrical tape on the Slit / dust proof glass you should see a White bar in the area where you placed the tape, on the copy
If the White bar is clean, then the problem is above the glass. Focus should be to Optics, Laser, and Main controller.

If the White bar area still has background then we are looking at anything in the Drum cavity.

old posted trys:
set Dip Switch 101 on the HVT to the "Down" position/ Set it to DOWN position (pointing to the word “DOWN”). FLIP IT UP TO " DOWN"

could set pre-trans to 0

the lamp>the lamp>looks like the lamp= AP KIT

or HVT/ GRAY in non image areas

Look at blowing the potential control sensor. Or as stated just turn it off and adjust dev setting to compensate. Blowing it clean is best.

I believe he tried this already.

Compensate what from the dev, the bias??

Lol...........

My IR105+ just does the reversed cycle of copying.
Instead of writing the black on the white,it write the white on the black
All the background set to black and writing(images) set to white!!!
My Canon has one new phrase " Black on the white"
Please help me to restore the phrase to the original one "Black on the white"

Well I didn't think it looked like wrong toner, usually copies are pretty crappy as well with the wrong toner but I will now reverse my opinion.
If toner is sticking where it shouldn't you have the wrong toner in there, like charges repel and opposites attract. Unless there has been some change in the laws of physics you will need to vacuum out every bit of toner out of the hopper and developer, put in the correct toner and either run 50 blank copies or do Copier->Function->Install->TONER-S. That is going to be a lot of toner on an ir105.


I had a similar experience with the wrong toner, scroll to the last post.

End users do get desperate when they run out of toner and a job must be printed, i can post some horror stories but it would take up too much space .
