Get your machine professionally serviced before it ends up being a paperweight. Making adjustments to SP modes without knowing what you're doing is just asking for trouble, and this is not a quick machine to PM or service even for a trained professional.

Rthonpm is right on! Sorry if you don't like the answer.
It's insulting to minimize what qualified technicians do, by thinking you can simply push some buttons and make it all better.
If your car needs a transmission, washing and waxing it, because you don't have much money isn't going to help.

Pale copy on a MP 7500 usually means that the developer is worn out and not carrying the toner correctly. Sorry, but there is only one solution and that is to give the copier a full PM kit. The process controller looks at the entire copy process when it adjusts all the settings, change just one part without the others and it gets very out of balance and can lead severe problems. It needs a kit every 350K but the drum should last 1.2 million copies.

What's this forum about? hmmm if you search for Copytechnet.com you get something that starts with ( Forums for digital copier technicians, laser printer techs, and fax repair techs ) That is really what this site is about. We have helped a lot of end users though. You are right in that we probably don't live and work in your town to get our salaries and paychecks. What we have done is worked long and hard to get our knowledge and experience. You come here looking for a magic phrase like Alakazam! ; your copier is fixed !. It doesn't work that way. A high speed digital mfp has to be maintained to produce good quality copies and prints. You say " this is a very used machine which i;ve got very cheap ". Now you know why you got it so cheap. We are sorry that you can't afford to get your mfp properly PMed, but that is what it will take to get your copies and prints up to standard. What I would have done if I were short on funds was get a smaller machine that had been maintained correctly to start with and then make money to upgrade in the future.

Sandmanmac, rthonpm and Lagonda gave you correct information. Get your mfp serviced correctly and DON'T " i've been playing a little with the service side, that cancel 107 red button " if you don't know what you are doing. You can make things much worse. Especially if you don't remember what you have done and can change things back. A good running machine can go to pot if someone changes SP settings without knowing what they are doing. Too many end users come on here expecting a technician to say " go into service mode and change SP xxx and SP yyy and you are done and everything is hunky dory. That is not in realty. Truthfully with your attitude you probably won't get too many techs sympathetic to you and willing to help you. I will now get off my soapbox.

try sp2207 and if that doesn't help for a little while call for service

Maybe you might try searching for a solution to your problems here first and by doing so learn what CTN is about? It is kind of stupid to do otherwise.

Do a memory clear on everything, it really works!
Don't.







Or, just hire a qualified tech.

Check SP 3001-001, SP 3103-001, SP 3101-002 and SP 3101-003. If SP 3001-001 is near max or all the SP3103 reading are 5.00, the ID sensor or either dirty or defective. You will need a service manual. If you do not have one, you can purchase one from Just Manuals, The Internet's largest selection of manuals ~ Instant Downloads. The face of the ID sensor is in a cutout in a l shaped metal bar across the bottom of the photo conductor unit. The metal bar will most likely be filled with toner as will the one toward the development unit. This toner will need to be cleaned with a copy vacuum. Do not get the vacuum to close to the ID sensor as static discharge could destroy the sensor. Use a lens brush to remove the toner from in front of the ID sensor then wipe the face of the sensor with a soft cloth moistened with water only. After cleaning the ID sensor, you will need to run the ID sensor calibration as shown in the service manual. If you get an SC when running the calibration, the sensor will need to be replaced.

Sounds like you did a memory clear, not a good idea. Now you need to locate the birth certificate and reinput applicable data, especially the LD data. It will not adjust itself back to specs. If it needs a PM to bring the CQ to acceptable, you're going to have to spend the money to do it, there's no way around that. Remember, It IS possible to turn the machine into a brick by screwing around with the wrong SP mode. It doesn't matter how good of a deal you got on the machine if you smoke a $1000.00 controller. Just sayin.

what a TOOL............do you think you are entitled to free help just because you cant afford a tech..
if you are so in need buy a manual..if you aint got $ then you do have time.............
and why do you think what will fix your old cheaply bought copier by pressing some magic serv codes...

This is about qualified techs helping other techs that have ran into a problem they can not solve. If we tell an inexperienced tech to do something and that tech does it wrong and really screws up the machine, then who's to blame? Your problem could be OPC drum, developer, toner hopper system, dirty sensor(s), dirty optics or dirty laser system. If you want to try to repair it your self, the very first thing that you need to do is get a service manual. The manual for this machine includes a Detailed Descriptions section. Use that to learn how the copy process works.
