Actually it sounds like you need to replace the drum cartridge.

I get plain paper or double when I received fax from my uf5300 laser fax.it print one page from 5 pages that sent and I got empty pages and double somtimes


Paper feed rollers and sheet feed pad dirty. Feed roller on top pad should be just below. Clean with alcohol. Papers have clay in them. Recycled is worst. It will glaze the pick up roller and pad.

When receiving a fax I get either big black plotches all over the page or thick black vertical lines running the whole length of the page to a point where I can no longer make out any of the information...


Try making a copy of something or printing a transmission report or journal from the "reports" menu. If the same problem is apparent on these printouts, then your drum unit or toner cartridge need to be replaced

3-INCH WIDE VERTICAL LINES RUND DOWN LEFT SIDE OF FAX MACHINE


Do your incoming faxes have the same marks?
If not you might find that the scanning part of your machine has a dirty mark on the glass or that the unit has become faulty.
Try and take a copy from the machine and print from a report or any print from memory.
If you have the black lines on both then i'd suggest getting a new drum unit, if u have it only on the copy I would have a look at your scanner glass and see if there is a dirty mark on it. if not maybe call out an engineer as the scanner unit maybe faulty.
Need anymore help msg me.

Poor fax printout quality


I would say you have a bad drum / toner cartridge.

Stuff you receive with vertical lines is probably the sender's dirty scanner.

Printing


It sounds like the toner is getting low. Take out the toner cartridge and rock it back and forth a few times to redistribute the toner evenly in the cartridge. If this makes the printouts look better, you should order another cartridge, as this one is getting low. I'm not sure about the L-100, but the toner cartridge for the L-120 fax is good for about 2,000 copies.

Smudging and overlapping


By smudging do you mean the print is actually rubbing off?
I am going to assume you are seeing some reprint on all printed pages.
If I am understanding correctly, what you have is a bad fuser, most likely a bad heat roller.
That is the heated area just before the pages exit the machine.
The coating on those rolls wear out with time, or may even debond from the aluminum. The ink does not then properly melt into the paper, sticks to the roller and progressively becomes worse.
Replacement of the fuser should resolve that issue. That's simply a normal wear item.

Ricoh aficio 1515f printing dark line down left side


If the print can be rubbed off then this suggests the fuser unit is not working correctly. It could be that the thermistor is covered with toner and making the machine think the fuser is hot enough when it's not.

The black line could also be caused by the fuser if one of the pick off fingers is coated with toner or has worn into the Teflon of the roller.

Does the machine show the lines when you print a page from memory - such as a counter or config page? If not, this would suggest the optical path is dirty. Try cleaning the glass and look at the mirrors inside the scanner to see if they are dirty/dusty.
