Hi Guys

have a colour reg issue on our C552

ive followed field manual page 728 (18.3.33 Printer 4-color: incorrect color image registration)

cleaned transfer belt (although not dirty)
cleaned transfer roller on door
fuser is brand new.

but color reg is off. and its not equally off over the entire page. the Y axis is ok at the start, but completely out at the end.

Look for the oil can at the bottom of the screen. If there is one, tap it to display any P codes.

I had something similar that turned out to be the LPH driver board.

Those are Life Warnings for M,Y,K imaging units

Means your color imaging units M & Y and K drum are past end of life. Might want to replace those first and go from there.

It started to happen after replacing the fuser unit

forgetting those C Y M drums etc. what else can it be?

I do need to strip down the machine and clean everything. but thats a mission and a half.

There is a loop sensor just before the fuser entrance that can cause lead to trail color alignment issues.

Are you able to point me to the location? ref a page out of the field manual if you could please.

unless anyone knows of a service guy that covers Cornwall,UK

It's PS41 and PS42 in the manual. I've never had an issue with them but others have. The picture is with the fuser removed to expose the sensors.

Cheers
i'll look tomorrow.

anyway to test? looking at sensor info in service mode?

I'd start by removing the transfer unit & cleaning the patch sensors & printhead glass might be all it needs.

However if the transfer unit or K image unit are way over life you will get this issue & they will need to be replaced.

Does it ever make a good color copy or print? The Fuser sensor usually only has a problem when running multiple pages in a run. If you open and close big front cover, machine
runs a quick calibration. Then run a print job. Is registration ok? :cool:

Agree, especially if issue appeared after Fuser change. Check both photo interrupter sensors(they are the same), actuators and spring.

Cheers guys

cleaned transfer belt
gave the PS41 &2 sensors under fuser a little wiggles and blow out lol
cleaned print glass with that rod thing. although the bloody felt end got stuck in hole. managed to get it out though.
cleaned paper dust bar

not sure how to test the PS4 sensors? couldnt see them in the service senor monitor

ran a pattern on A3 after, seems ok ish. hopefully it lasts...

printed full color pages of C/Y/M/K, they are somewhat ok. but a little cloudy in places.


really could do with a engineer that covers Cornwall, UK area.

P-22 occurred 63 times! color registration failure.


IDS front and rear
IDS shutter solenoid ****
Front side board FSB
and print control board PCBR
Bad drums devs and transfer belt can not be excluded.
Half-tones should show a problem there.

Check you IDS levels under <state confirmation>.

the issue is back. but im not sure where to start on your message.

first off maybe i just clear all codes/stats?

all colours are offset and blue is marking across further pages.

ive found the IDC/registration sensors in the field manual, i'll try cleaning/re-seating them first.

Check the voltage levels under state confirmation under in service mode for the IDS sensors.

Should be like 3.0 Max but more like 2.8. Both of them should be around the same value.
The lower that value the less reflection comes from you belt.
If IDS1 and IDS2 don't match close it shows a problem.

Toner on those sensors is a common thing.
Remove the belt open the shutter and clean the sensors.
Check the shutter mechanism while you are at it works with a solenoid.

can seem to fix the colour registration issue out. im not a engineer to get access to parts, im just a IT guy.

We had a similar problem with a C220,and solved it when we replaced the transfer belt.

Look up "5.5.102 IDC registration sensor/F (IDCS/F), IDC registration sensor/R (IDCS/R)." in Service Manual--they are under the Transfer Belt--need to slide lever to left to clean the sensors. Do this first thing....

Oh Noes! You just admitted to being just an IT guy,
I'm surprised you have not gotten hardcore technician-threats, yet.

Anyways, give the count on the transfer belt and IUs from service mode.
Also level 2 history from service mode.

How does he have 0 rotation time for L1 (C) & L-3 (Y) and only 1241m for L2 (M) and a whopping 3820 for L-4 (K), but getting L-2, L3, & L4 oil can screen?!
That info coming from Warning in Counter from SM don't remember that being there,
but instead in Life (l just checked my c654) maybe just a oddity with the cx52 series?

Looking at the initial print, looks like the Magenta IU or Transfer Belt secondary roller (so transfer belt):
ECA, I say your copier needs at least one expensive consumable replaced.
