Colour Banding On Print Jobs

Hi there, I'm trying to figure what I can do as our technicians are stumped with this problem we've been having with our printer. Basically when solid colours are printed, the printer has a high noticaeble degree of colour banding (inconsistant colour spread leaving noticable lines in printed material) which is problematic. Despite our service tech trying to fix it (replace components within like drums), the problem exists. What do you think could cause it? It has nothing to do with the files being sent to the device but it's definitely hardware-related. Could it be lack of humidity affecting the unit? We live in a drier environment and the office might be as a result. The paper settings are set to the right gsm and we have the Ricoh correct toner. We've done both the internal Ricoh calibration and the Fiery colour-management calibration using the Spectrometer. I'm sure there must be a reason for this occurring? Or is it potentially faulty and needs to be replaced?

You probably can not repair it. I will say this though, be careful to get the right labels for it.

Are the lines dark or light? You can try replacing the toner to see if that clears it up.

Also, go into the user options -- if you see a setting for something like "toner save mode" turn it off. That can cause poor copy quality and is sometimes turned on by default.

SOURCE: My Ricoh CL7000 keeps asking to replace the yellow

The toner cartridges for the CL7000 have microchips embedded in them, so the machine knows if it's not a new cartridge. Was the cartridge you put in brand new? (And was it a genuine Ricoh cartridge?)

On those printers, the toner is pumped into a developer system and mixed with the developer before making the image. In the developer unit, the density is checked, so if it's not seeing the right mix there, one of three common problems could be causing this.

The more likely solution is to replace the yellow developer unit, which comes as a whole unit and just slides right in. That will reset your density levels and should correct the "load toner" error.

There is a spring and cushion mechanism that the toner cartridge sits on -- this mechanism can easily be popped out of place and cause problems loading the toner. Take out the yellow toner as well as one of the other colors, and see if the little black circular piece is sitting the same way for both colors. If not, just pop it back into place, using the second color as a guide.

The other likely possibility is that the yellow toner supply tube is clogged, but that doesn't happen very often. To test if it's clogged, take out the yellow toner cartridge and the yellow developer unit and turn the copier off. Use a vacuum to provide suction at one end of the tube (the toner end will be easier) and put your finger on the other end (the developer end) and see if you feel the vacuum's suction. If not, there is probably a clog somewhere in the line.

If there is no clog and you can feel the suction, you may have a bad toner supply motor.

As a side note, if you find the problem and fix it, you might still have to put a new yellow toner cartridge in to get the machine running because it will think the cartridge you already tried is empty.

Hope that helps!

Try with the adjustment settings either in the printer or in your system. If the print quality is still low, Replace the printer. You may have warranty replacement.

I have a Canon MP 210 printer, I put in a new colour print cartridge, now it shows the Cartridge is empty and when it prints the colour is only pink, I have checked that the print cartridge is installed...


I've heard of similar things happening and being corrected by opening its easy print software and trying to print something there to see if it's a driver issue. Also you can try manually correcting the color
