[aliomr]

Hello,

i have a ricoh aficio mp c2500 color copier and it driving me crazy :@

when i put a paper on the glass and give an order to copy , the machine start copying fine
but the copied paper has completly black part all the way down but if i put my fingers under the touch panel and give a slight push up it works fine
and if i press down the black blank part gets bigger , i dont know what the hell is this , the scanner works fine and no proplem with it because as i said when i left up it works fine and the copied paper is good , but i dont know what to do , please help

i can post pictures to make it easy for you to help me , but please give me some advice , i know its something easy to fix but i cant figure it out

i can also explain the proplem in a video to make it easier to understand the proplem , please help

thanks in advance

Printed copy coming out black? and ok if you push on the ops panel from underneath?
Probably easier if you make a video.

if i print from a computer it comes out fine , when i print a test page from the machine it self , it also comes out fine with no proplems , but the proplem when i use the copier

what i meant by pushing ( imagine this with me ) , i put about 4 fingers under the panel then i lift the panel up ( not so hard about a couple millimeters ) it copies the paper just fine with no proplem.

if i put 4 fingers on the panel and push down , the proplem gets worse and the black area gets bigger


p.s : if i lift or push up or down from any place the same thing happens , its not limited to the ops panel area

Re: Proplem with ricoh aficio mp c2500

Possibly someone has been leaning on the left corner of the panel and has deformed it down. Usually causes skewed copies but if it is deformed enough, the projection path can be changed enough to cause black copies.

On many of those scanners, if you take off the left side scanner cover, you can adjust the position of the scanner and tighten the frame screws. Just be very careful because if you position it wrong it can cause more copy image issues.

remove covers from left hand rear corner and square it up possibly using some shims. or perhaps just loosing the screws and lifting in place and retightening. good luck might take some time but you'll get it.

A dead give-away for a skew scanner on any Ricoh mfp is if you lightly tap on the copy glass and you can hear it ping like the glass is lose in the frame, then you know the scanner is not sqaure and the left front edge of the scanner frame needs to be lifted. As the glass cannot be skew, it is always an easy way to check.

there is a quick solution , you can fix an arm with adjustable length to sustain scanner in the proper level , to get right copies.

Re: Proplem with ricoh aficio mp c2500

Grab under the left front side and torque the scanner up a bit. Not very scientific, but it works if the problem is due to people leaning on it.

The Aficio 2035/45 had a support brace that mounted on the left side of the copier and scanner for that problem. Might work here too.

Re: Proplem with ricoh aficio mp c2500

I wish Ricoh would design their machines with a post left front under the scanner!

This will solve so many optical issues!

Re: Proplem with ricoh aficio mp c2500

i figured out the problem , the chassis from the left side was deformed , it was bent down , i grabbed a car lifter ( that lift the car to change tires , i placed it between the scanner and the machine it self , i supported it with a plate of wood to prevent cracking the plastic , then i tightend the screws well , then i gave it a couple of pushes untill the deformation gone ,

another problem appeared , whe i copy a b&w paper it copies fine , when i copy a color paper the paper is messed up very bad with black hues and white areas are yellowish , i came to conclusion that the measuring plastic ( the one with paper sizes written on it ) is the problem , when i place it with the exposure glass the copied paper is messed up , when i remove it , the copied paper is great i think its something with the scanner home position or something but again the b&w copying is good , what could be the problem , i'm adding images to make it easy

Re: Proplem with ricoh aficio mp c2500

Are you sure that you did not push up the scanner too far now? The scanner assembly is fairly sensitive and if it is out of square, this affects copies by causing shadows and lines that don't exist on the original copy.

I normally look at the post where the scanner (left side) and machine meet. Generally there is a gap in the covers there, that should be parallel from side to side (horizontally) if this is not the case the scanner is either too high or low, whichever the case, and needs adjustment.

Also like i said before, if you tap on the glass it should sound like a dull tap and not a ping as if the glass is lose. If this is the case, the scanner is out of square and needs to be adjusted.

by a ping you mean that the glass is touching the exposure lamp so it makes this sound , right ? , also why does it copy good without that plastic bar , its just doesn't make any sense , i'll give it a slight push down with my hands to see if that works , thank you very much , your a great man , if you need anyhelp with softwares or something give me a call , i'd love to help you
