SOURCE: Dirty Background on Printouts

The most likely problem is not with the drum unit but rather with the developer unit and there is a leakage current within the unit causing the 'ghosting' on the printed images.

I would suggest that you replace the developer unit within the system. It is quite possible that the waste toner blade is contaminated with debris from using non-OEM toner within the unit. Therefore leaving residual toner particles on the surface of the drum.

Try this solution and see if that corrects your problem. This solution can be applied to virtually any laser printer, copier or MFP device in the industry. The problem is nearly 99% of the time related to CHEAP toner cartridges that are refilled or refurbished and the company doing the work does NOT replace the cleaning blades within the units, and they use a generic polyester-resin toner that does not conform to manufacturer standards.

I worked as a Design Engineer for Kyocera-Mita America for nearly 6 years and have seen this problem many times in the industry. The price you save on using recycled cartridges ends up costing you more when you have to replace a developer or drum unit.

Hope this information helps you out.

Cheers,

Keith

It's probably happening because the cleaning blade on the drum needs to be changed or replaced.

Loud toner error


The machine does not use the toner directly from the bottle, it goes thorught a developer chamber filled with developer powder. Then the toner is charged and can "jump" over to the latent image of the drum.
In this developer chamber, there are some small gears (2-3 tiny gears) that may be worn out. Some developer may have entered the "gearbox", and the deveoper powder is very abrasive.
The teeth of the gears will eventually stop to contact and mesh up. The internal parts of the developer changer stops to revolve, and there is no toner mixed with the developer.
You can see that there is a build up of toner, but it does not enter the developer unit. These gears have to be replaced, and I allways change the developer powder at the same time.



mp 2000 developer gears-2rhlv5r3sdqqpeuzs0ozcjtp-5-0.jpg These gears must be replaced it they are worn. The image shows a brand new part that contains the gears.



mp2000 developer toner input side-2rhlv5r3sdqqpeuzs0ozcjtp-5-1.jpg This is the side of the developer unit where toner enters the developer unit. With defective gears, the developer unit can not pull toner inside of the unit, and the toner builds up in front of the unit.

The gears are cheap, but will often result in the need of new developer powder - and that is expensive.
If print quality does not have to be too good, one can use the old powder and save money. Some of the powder is lost during use, and leaks. There may be some dust in the developer too.
In order to get high quality several parts may need to be replaced.

It is quick and easy to change these gears, just a bit dirty job.

I have a problem with my photocopier RICOH MP 5002 despite replacing new drum new cleaner blade and new developer my copier still copy very faint copies what could be the problem


when you replaced the developer, did you clean the "mag roll" of baked on toner? Very common problem on this model. Of course you initialized the SP mode 2-801, and 2-805 right? -Carl

Toner leaking and low quality copy


I would check the transferbelt/wastebox/cleaning unit to see if it is full or have a problem with cleaning.
If it is full it will make a soundt as some toner is forced out of the wastebox. I've seen a few examples of cleaning blades that does not clean smoothly too. When the blade moves toner scatters.
It it is full, empty the wastebox and change the cleanin blade.

If not, check the drum and the drum cleaning. I've had a "jumping" cleaning blade on the drum too, also resulting in toner scattering inside the machine. It that is the case, the blade must be changed.

In order to make this machine run kind of OK, you need to keep it super clean, change developer and other parts at least as often as Ricoh says in the service manual.
Make sure you have the latest firmware model, and the right toner.

It is a machine that runs dirty, and based on the POS Adonis series of machines from Ricoh.
For other viewers here, stay away from the Ricoh Aficio 350/450, 1035/45, 2035/45 and newer models like the MP 3500/4500.

You will notice companies that sell copiers from differente brands often have decided not to sell this model from Ricoh, and just choose a different make/brand as their machines (in this segment) are better.

Background on copies, possible dirty charge roller , I cleaned all optics is there an adjustment to perform to help eliviate this background


Hi,
yes it could be chatge rollers fault, but how many copies does developer have? I would clean the charge roller with water, dry it, and change the developer. On these digital machine, when you have backround wich is dark, these means that developer is worn out and you need to change it and clean developer cylindar. When the optics is dirty the image will be light, not dark!!!!! Only on analog copiers when optics is dirty the copy is dark, and when the developer is worned out the copy is light!!!!

Printing black on paper


Some of these machines will allow you to printe a grey scale test copy.
This will readjust the fax machine back to a nominal mode.
Not knowing how old or how long the machine has been serviced, background can be caused by dirty optics somewhere in the machine.
A remanufactured drum unit can cause this type of problem, (defective unit)
Competitive toner in the toner unit can cause poor copy quality.
Reinstall the old cartrige and see if the problem changes.
Not knowing if the machine has a seperate drum unit and developer housing, it would be hard to answer anything else.

Poor quality since changing ink.


If you didn't have this problem with the last toner than more then likely the new one is deffective. It seems to be having a ghosting issues which happens when the dr blade inside the toner does not clean properly. You need to try another toner cartridge.
