ricoh 1035 laser problem

[cristian]

I have a problem with the quality of the copies. After i have changed the LD,cleaned, copy.jpgoriginal.jpg i have the followings(photos).Of course i have done 2109 with 1,2,3,4, but at 2103 with 1,2,3,4 with a value of between -10 and 50 it enters in SC 322 and with 64 the copy is as in the photo. What adjustment should i do more...?

Re: ricoh 1035 laser problem

If the prints are ok, the optics are clean, the laser unit is ok, then the BICU-Board may be the next suspect. Could also be a faulty memory dimm.

Re: ricoh 1035 laser problem

Was the Laser diode unit replaced with a new one for the proper machine or was it taken from another machine? The laser diode for the 1035and the 1045 are different part numbers. If you have to set the laser diode power all the way up to 64, the diode is about to fail completely.

BICU-Board may be the next suspect. OK , i will replace it also.
Could also be a faulty memory dimm.Please be more specific.
Thank you.

I have two dead 1035 machines due to mechanical problems in the warehouse.If i remember well , all of them were functional , and i have to get from them some motors, boards, etc.i have use only 1035 parts.First diode gave me SC 322 whatever i ve done.The second one has put me out of sc 322 but the quality of the copy....Anyway, 2-3 years ago, i have had a similar problem, i have forced some settings to maximum(or minimum...) for few copies and the quality has come back to normal gradually after aprox 10 to 20 copies . But unfortunatelly i do not remember what i have done...On the right side of the diode there are two small blue power regulators.Did you know how it react the diode when i easy decrease or increase with a srewdriver the values?

Almost forget. Prints are the same quality....And as observation , indeed i have some memory problems with the copier, means at printing the machine forget to print some jobs even with 20-30 kb(1-2 word pages). But not every time....

When you said you changed the LD, you do mean the entire laser unit, don't you?

First of all i have changed the entire laser unit. Result :sc 322. Second i have replaced and clean the door switches, both, including the one near fuser.Result >sc 322.I have replaced then, the laser diode with the old one, to the new replaced laser unit. Result> sc 322.I have replaced the laser diode with the new one to the old laser unit.Result> out of sc 322, but the copy is as presented, and only for values of laser power higher than 50.So seems that the problem is in the laser diode, or, there is a complex of other more...I will also change the poligon motor when i ll get back to work on monday, and i will see also the BICU board.
Any way, after i have looked in the interior of the new LD unit i have see that the poligon motor is not the same as in the old one.The board is a little bigger and the position is different, fixed in the other sets of holes. I will also try to change the poligon motor to the new ld unit with the old one and to see what will heappened...

Re: ricoh 1035 laser problem

If time permits, before you replace parts try running 2109 6, then set 1 and 2 to the default values, then run 3 and 4.
If that doesn't help, when you have the laser unit open, check to make sure the synchronization sensor isn't blocked (the sensor will be almost opposite of the laser diode). While it hasn't happened to me that often, I have seen that senor go bad. And that would be more likely the cause of the problem than the polygon mirror motor failing.

Re: ricoh 1035 laser problem

As slimslob has noted the laser diode assy for the 1035 and the 1045 are different,as are the polygonal mirror motors.
I noticed you have another thread about the same issue on a 2035, and although the ld and poly mirror are the same for the 2035 and 2045, neither will work in the 1035 or 1045.
Just as a suggestion, it may be best if you check the part numbers of the poly mirror motors and LD ( if possible ) with the appropriate parts manual, just to make sure nothing has gotten mixed up and to make sure they are supposed to work with what you have.
It will possibly save time in the long run, and once everyone is certain of what you have in which machine we can possibly offer some better help.
If you do not have acess to the manual, you can post the numbers and we can tell you what you have.

Re: ricoh 1035 laser problem

Looks to me like a PCU issue. On a B003, the flat spring contacts that contact the charge roller terminals must be bent up a little to ensure good contact, or you will get an image that looks like yours.

Re: ricoh 1035 laser problem

For just the background issue, I would check/clean the development roller. Toner film buildup on these can cause quality problems.

Re: ricoh 1035 laser problem

Thank you all. I have learn and remember a lot of important things about those machines, that i love due to their fiability.
Of course i have checked the working parts, as much you can with the eyes.Of course i have run all the possible tests and setting according with all the previous posts regarding those machines.
I have solved the problems as :code SC 322 at both machines 1035 and 2035
for the 2035 the fault was at the connectors near the fuser.I have cleaned them , but won t work untill i ve change them.
for the 1035 something was damaged at the LD unit. I am not sure what was exactly the fault but i have start to change gradually piece by piece, all the boards and small boards for the two LD units that I have, and knowing one is working and the other was not working.. I have had 12 possible combinations. I have succeed at the 7 th. Why i do not know what the problem was ? Because the poligon motor board for one of LD is different (bigger board and turned with 180 degrees as position, other lenght for the cables, and still working for an 1035 that i have store it because i have to take him the main motor for another machine). I have turned it in the oposite direction and , voila...it s working.Strange thing but it s heappened... The only minor problem left at this 1035 to solve it 100% is that sometimes, in 30% of the prints, the machine forget to exit the prints, and as i have observed, only for word files. The PDF files , jpeg, etc working good. I have reinstall my office, yesterday but today after 10 prints OK , the machine stop printing 2 pages in Microsoft office word. ..After an restart the problem is the same . I have give him to print a page in PDF and was working without problem.
OK. Than thank you all of you.
