Printing too light

For understand the issue, little bit technical knowledge required: Take half test page, check how much dark image formed on paper, check on cartridge drum how much dark image created?..(half test page: while printing half of the page switch off the printer, take cartridge out as well as take half printed page)If half page print quality is good on paper: Fuser faulty(teflon sleeve)If half test page print not good & image on drum is OK: Fault with Transfer roller or its bios voltage contacts..If there is proper image on paper & image drum: Problem with laser scanner assembly..find the problem, then remedy is easy..

Hp 2500l prints a dark line horizontal down each page. Can we clean drum at home?

A dark line on the hp 2500 series can come from the drum You can't clean it at home), it can come from a toner cartridge, from the fuser unit and from the optics.
Step one - check if the line in all colors, run copy quality check through Menu and diagnostics, if the line is only on one color your problem is the toner cartridge.
Step two - if the line is on all colors, take the drum unit out and look at the drum, if you see the line on the drum you need to replace the drum unit.
Step three - stop a print in during the printing process by turning the printer off, take out the drum and look at the printed paper under the drum, if the printed page is clear of line your problem is in the fuser.
Good luck.

Bad photo quality after changing drum

your laser printer
1) print color quality is now distorted that means print skew (technician called)
2) print tint means the print color not enough density,
3) print mottle means print dirty
you may try
1) print distorted--- find out the skew adjustment from your printer manu, it is adjust the image before transfer to the drum.
2) print skew could be happened when the drum replace install not very accurate, so install it more carefully.
3) print tint---you may increase print density from the manu, not fix,
4) print tint---the toner caridge near life cycle or using the less compatible toner. so you have change the quality toner or cartridge (if near life cycle) to improve quality photo print
5)print mottle---toner quality ? or cartridge near life cycle also cause print dirty paper,

Dark background print in minolta EP2050 mach.

Replace controller/ interface board. The next step would be the regulator board. If you must keep resetting the ATDC and receive different values ( assuming that the ATDC is new) then the problem is back. What supplies/ controls the ATDC? The controller, but forgive me if I am wrong, there is a small interface board after the controller that the ATDC is plugged into.

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.
