[CQ] savin c2525

[BUDDYWF]

I HAVE A CUSTOMER WITH A SAVIN C2525 COPIER. THE COPIES COME OUT WITH THIN BLACK LINES TOWARD THE FRONT OF THE COPIES. I HAVE CLEANED ALL 4 DRUM UNIT, THE TRANSFER BELT CLEANING UNIT, AND THE OPTICS. CHECKED THE FUSER ROLLERS AND THEY LOOK FINE. CLEANED ALL THE ROLLERS. RAN ALL FOUR COLORS INDIVIDUALLY AND STILL HAVE THE FINE LINES. THEY FADE OUT AFTER ABOUT 2 INCHES. WHAT AM I MISSING?

Re: savin c2525

CAPS off please.
You say "copies". Do you mean "prints" as well? Or does it only happen in copy mode?

Re: savin c2525

if its through adf id look at margin shift maybe thats the "line" this fella is chating about..

Re: savin c2525

Im not sure I am picturing what you mean. When you say front of the paper do you mean the lead edge to trail and are the lines vertical or horizontal from the lead edge, are they any certain color or just black marks, is this on copies only or does it print with lines also and if its copies only is this while using the doc feeder or just off the platen glass. You can get lines from dust on the optic mirrors, or a line if the DF is out of alignment, its if its prints also then it more of a PCU/transfer issue.

Sorry about the caps. I have only run copies, but the lines are there whether run through the adf or put on the platen glass.

The lines are from the lead edge to the trailing edge. They are heaviest toward the front edge and get fainter as you go toward the back of the copy. They are black lines, and are there if using the adf or put on the platen glass. I have cleaned the mirrors, all pcu unit, and the ibt cleaning unit. Nothing has helped. Any more advice.
Thanks

Re: savin c2525

how about when you dont use the optics, like counter sheet or smc lists, printer test sheet.

Re: savin c2525

It sounds like you have a problem with a pcu, probably black. Is it ready to be replaced? I know you said you cleaned the pcu's, what does that mean? The charge roller is the only cleanable thing on these, and that doesn't fix many issues. Old developer/dev unit can also cause a problem like this. What's the SMC say about the maintenance count on these items?

I will try that and let you know.

The pcu's have a cleaning blade & waste toner in them. I vacuumed that out, and cleaned the pcr. I just took over maintenance on this machine & do not know the history. There is no service log with the machine.
I will try to find some facts on the supply items. May have to try a new black pcu.

Run a SMC(logging data). This should give you an idea on the condition of your PM parts.

Re: savin c2525

One thing that is often overlooked and causes strange lines (that are not the whole lenght of the page, and that fade along their length) is the scanner unit itself. If heavy objects are put on it, or people lean on it, it can get bent out of alignment (especially the left front edge that has very little vertical support).

A quick way to check this, is to line up the lower horizontal (closest to the op panel) front edge of the copy glass with the endge of the op panel. Now remove the slit glass cover (on the left) and check if the left vertical edge of the glass is 100% aligned with the metal frame that houses the slit glass. If there is a gap on either side, then the scanner frame is either to high or low. Adjusting it in either direction with lead you as to which way if has to be adjusted to fix it.

Once aligned propperly, the "magic" lines, should be gone!

Re: savin c2525

One way to elimiate optics vs a pcu part is to look at the marks on the page, there is an erase margin around the outside lines caused by the optics will not print in the erase margin they will only show in the printed area, lines caused by a charge roller or other mechanical part will go from edge to edge through the erase margin. Also run a B&W copy in full color mode if you get all sorts of colored and B&W lines in a full color copy when there is no color then usually its dust on the glass being copied. If its still only black lines then I would replace the black pcu
