Re: RICOH MPC 4502 copies with vertical lines

I would do this first...
1. SP2109 003 -> 1 (1dot vertical), 2109 005 (select color) --> Copy Window -> press color mode... 3 pages A3 for each color cmy and b/w (press black mode).
(When the lines occur in each colors + bk so you have to check the cleaning unit, ITB unit and PTR unit.)
2. Interrupt the copying process by door opening before the paper reaches the PTR unit and then the fusing unit.
3. It is also possible the cleaning unit of ITB does not clean properly. The pm counters have been checked?

I would go one step further and replace the complete Black pcu. It looks more like a drum/ charge roller issue. Does the drum rotate freely if you turn by hand, or does it bind and make loud rubbing noise ?

it would be nice if you told us the lifetime of the pcu and total counter...

The pcu condition is good, rotate freely and no rubbing noises.
Meter reading :-
Copier B&W : 55258
Printer B&W : 309553

we have placed order for new black pcu and will replace it.

Thanks for sharing the valuable knowledge. it was helpful and thanks again to all

That is the black. What about the color?

First thing I would have done would be to check PM count on PCU, stop it before fuser check to eliminate fuser, are the lines always in same position. I presume paper is LEF, I hope the grey background is from your camera.

Re: RICOH MPC 4502 copies with vertical lines

if u got into sp mode, before selecting the mode, there is a maint tab, select that and then do a print out. the k gets alot more usage than the counter shows. as its used in color as well. ive seen counters at 50k and the pm counter show 100k

MP C4502/5502 do not have maintenance counters as an option from the main SP menu.
