Ricoh mp2501

I thought there is an error code when you don't install the toner hopper
????

if I'm not mistaken the code appears only on the A4 like the mp161 etc.

On some entry level models the laser is disabled when there is not toner bottle installed.

Had same problem a year ago... Turned out to be the laser unit, had to clean polygon motor and glasses inside, caused by toner dust from the bottle. If it was dirty inside the toner hopper... Probably there is toner dust inside the laser unit.

Light copies and SC392 point to a bad or dirty ID sensor. You may also need to clean the optics including all mirrors.

Thanks, checked this ...

Original Ricoh OPC? Sounds exactly like the problems I ran into when I had to use generic lime green drums for the AF1018. You can turn up the Dev bias but this causes other problems down the line

during PM did you clean the inside of the machine along with laser glass?

did you init/reset the parts life?

what exactly did you do besides replace parts?

third party crap toner being used?

so many questions .. sooo little info.

As explained above, did everything, including cleaning optics and laser unit, maybe not sure of toner, toner from client purchase but seams original too, Thanks

Are the pages gritty to the touch?
Maybe try another toner supply unit...might not be adding toner correctly.

Was the first printout (or copy) after your PM good are - right away - too light?
Were the printouts also light before your pm?

sorry, now in better English:

I would try adjusting the Dev Bias as a test. Factory is -550 drop it down to -900 to see if it prints darker. If the prints are darker but the copies are still light next I would adjust scanner gamma. All workarounds we had to come up with working for a company that insisted on using Katun drums and type28 developer on these. But be warned the drum cavity will get dirty real quick and toner will build up around mag roller if you have to adjust the Dev bias that low. Parts also won't reach yield

Clean the machine's air/ozone filters, and the ID sensors. Do a forced toner supply till the image looks like you want it, then reset developer again. If the forced toner supply does not increase the image density, then your problem may be a toner supply, or drum ground issue.
