Ricoh FAX2900L printing too dark

I just replaced the toner cartridge and now it's printing too dark to even read. I can't find any key or function to lighten the print. How can I lighten the printing?

Check the scanner white roller witch is under the front cover where you feed in the paper to be scanned sometimes this gets dirty you can take it out by releasing the levers on each side..this also sets the density for copying.. if you have just put a newe cartridge in also check that it is seated properly as the contacts for the charge might not be connecting properly

Pages are printing dark (like there's too much toner coming out)


Are you using a compatible toner, or original..
If compatible, go into the settings and lighten the print.
If original, could be faulty... but I would say it's the toner.
Try another if you have one.

Print copy is very light. Is there an adjustment?


Usually light prints on a Brother just mean a bad toner cartridge, but try these first:
  • Most Brother drum units have a slider that you push back and forth. It's probably blue plastic. Sliding that wipes dust off a charging wire in the drum unit, where cleanliness is essential to getting a clean, dark print.
  • While you have the drum & toner out, look inside the machine for short, shiny steel wires on the inside walls. Those wires contact metal in the drum unit to transfer the high voltages required to get toner onto the paper. Clean those wires and contacts with a little wire brush or even a pencil eraser. Chances are, you've been pulling out your toner/drum assembly while this problem has been bothering you, and that has probably cleaned all the contacts enough.
  • Look at the slot in the top of the drum unit where you can look in and see the drum. The laser shines down through that slot to draw the image on the drum that will eventually be your print. Look up into the top of the chamber where the drum-toner sits, and you'll find a skinny glass window. Gently wipe that clean. Any dust or toner there will lighten your print. Be careful not to knock any of the tiny, black levers that stick up into the bottom of the area. Those are paper sensors, and they have to be delicate, so they can be moved by the paper passing over them.
I expect that none of these will help, and you'll have to get a new toner cartridge. If the old cartridge is still new, take it back to the store along with print samples. Maybe even bring the printer so they can test their toner themselves. They might just swap it for a fresh one; it's worth a try.

Hp laserjet p3015 prints really dark. how can i lighten it?


EconoMode This product has an EconoMode option for printing drafts of documents. Using EconoMode can use less toner and decrease the cost per page. However, using EconoMode can also reduce print quality. HP does not recommend full-time use of EconoMode. If EconoMode is used full-time, the toner supply might outlast the mechanical parts in the print cartridge. If print quality begins to degrade under these circumstances, you will need to install a new print cartridge, even if there is toner supply remaining in the cartridge. Enable or disable EconoMode in any of these ways:
  • At the product control panel, select the CONFIGURE DEVICE menu, and then select the PRINT QUALITY submenu. EconoMode is turned off by default.
  • In the embedded Web server, open the Settings tab and select the Configure Device option. Navigate to the Print Quality submenu.
  • In the HP Printer Utility for Macintosh, click Configuration Settings , and then click Economode & Toner Density .
  • In the Windows PCL printer driver, open the Paper/Quality tab, and select the EconoMode option.

Printed pages are light on both sides of page.


This is usually a sign that the toner cartridge is running low on toner. Replace the toner cartridge and see if the problem persists. If not, then problem solved.

If the problem persists, try adjusting the darkness settings in the printer settings when you are about to print. Sometimes even one notch darker can make a large difference.

Dark background on Dell 1700 printing


Faulty (or wrongly) remanufactured cartridges can produce a 'background' to a print, which can be even across the page or have a mottled effect.

Do a printer self test page (press the arrow button).

put the old toner cartridge back in and do the same.

Does the background show with the old cartridge ?

If it does, its a drum unit problem, if not its a toner cartridge problem, and that should be under warranty if you've just replaced it.
