ricoh 1035

[cristian]

I have a problem with an Ricoh 1035.
On the copy there are some hundred of stripes as in the photos.
What i have done till now:
- i have change the drum with a new one
- i have clean the optical parts
I have insert in the attachment : the original of the copy , a copy with the old drum and a copy with the new drum.The stripes are still there , so is not the drum problem.
The stripes are not in the same position ....
The copy is A4 normal and the stripes appear perpendicular on the exit direction.
The lamp seems to be OK.
Anyone has encounter this problem?

You need to follow a service manual and section about replacing laser unit . The problem you have got is related to the laser pitch adjustement settings .

[cristian]

Thank you .I need to replace the laser unit , or to modify the pitch adjustment settings ?

[cristian]

Obviously i think you are right , because in the printer way the copy is perfect.

i do not believe, that its a laser issue, check the charge roller and its contact instead

I have checked the surface of the charge roller and seems to be oK, means clean.About the contacts, do you mean to check the contacts to the right - left of the roller ?Because seems that there are OK...

Obviously i think you are right , because in the printer way the copy is perfect.

If the prints are perfect, it's not the laser unit or the drum. Got to be optics somewhere. Try lifting up on the left side of the scanner. If it gets leaned on it can cause lines (have never seen it that bad before from that though), but worth a try.

Charge roller contact on the drum unit.
Clean contacts on the back of the drum unit and frame.
Pull lightly on the contact springs on the back of drum unit.
Clean the bushings and contact springs inside the drum unit.

The laser would cause light and blank areas, not black.
Black lines are caused by intermitent lack of charge or bad cleaning blade.
Your image shows random lines and sample 3 right side has the pattern that is on the sharge roller.

i think they are all right. but i think try first the optics unit the lamp. mirrors, and the lens unit. clean them all. then the PCU carriage,clean and/or replace the charge rollers and bushings, the cleaning cloth/ roller and specially the cleaning blade. try the simple ones first before we go to the laser unit.

[Fearless V K]

Are the lines present on the copy counter sheet, SMC report, internal test pattern, or print from a PC?

If YES, then most likely drum charge and/or cleaning problem.
If NO, then it's most likely the optics or SBU (and I mean the scanner optics, not the laser unit or slit glass).

[mikadonovan]

Run your beam pitch adjustments. Aside from the lines, I notice the image has has been stretched a bit. That could also mean a problem with the SBU, BICU, or MAYBE the HDD. After reading all posts on this problem, I'm leaning towards a bad BICU. Run an SMC and tell us what SC codes have been popping up.

This happens a lot when I service these....machines, You have to clean everything in and around the pcu, especially the contacts on the rear of the pcu and the two contacts that look like square spades that sit at either end of the pcu, just above the charge roller ends.
And don't forget to clean inside the machine too, the inner backwall where the contacts meet. There's no short cut to servicing these machines. While you have it all out, Clean it! Otherwise you just end up frustrating yourself. These are messy machines and crave a lot of cleaning.

Also make sure that the affore mentioned "square spades" are in the correct position and not bent out of the way, that'll cause this problem too

Happy cleaning.....

problem solved

I have succeed to solve the problem.
First teps:
- clean the drum unit completely
- clean the optical completely
- clean the scanner motor
- spray the lamp guides- right and left
Make some copies.Nothing.The same stripes.
Second steps:
- in SP - SP 2001 - COPYING - AT MAXIMUM
- ID SENSOR PATTREN - AT MAXIMUM
Finally a copy .Not so briliant ,but still a copy....who resembles the original,the same dimensions , but unclear....
Then , return to SP 2001and all the followings step by step - copying - 1560
- ID sensor pattern- 560
LD1 - 50
LD2- 50
LD Beam Pitch adjustment : for 400 - 100
for 600 - 220
Development bias: Dev. bias - 540
I.D. - 380
Put the new drum , and the copy is perfect.
What step was the decisive ?Supose to be the cleaning of the exposure lamp rails....Anyway , it worked..
Thank you for advices everyone.

Hey, problem solved and it's Friday. Always a good day.(unless you have to work Saturday)

[copytrust]

since you said that the machines works ok on printer then lasers,charge rollers wont work......... your problem is optics section check everything there starting with mirrors and the lens............
