Question about Samsung SCX 4521F All-In-One Laser Printer

1 Answer

Samsung LaserJet prints completely black pages

I have a 2 month old Samsung SCX-4521f all-in-one printer. It worked fine for a while, but every time I print something now, or receive a fax, it simply prints a completely black page. The whole page is coated with toner. Any ideas? It seems like it's probably hardware (because it happens with faxes, too), but I've never seen anything like it before. SH

    I get either a wide fuzzy-edged black strip on the right or the full page black. It is intermittent. After reinserting or replacing the toner cartridge it sometimes clears up -- for a while. Letting it sit for a while sometimes does the trick. I cleaned the cartridge contacts with alcohol on a q-tip, opened and closed the front and back panels, cycle the power, let it rest over night, you name it. It doesn't seem to care what I do, it just starts working right for a while, up to several days, and then bam! back to black pages.

    I remanufacture toner cartridges and am about ready to tear the unit apart and see if I can find the problem. Will report here if I do.

We had the same problem with our SCX but we replaced the Part #: SCX-4521D3 toner/drum and it worked fine after that. We replaced the starter cartridge with a 3000 print capacity cartridge.

I have a samsung scx 4521f printer and wen i print thru it black dots on the paper appears..

This is likely to be either residual toner left from a previous leaking toner or that your toner has leaked in the printer. I would recommend running off 30 or so pages and seeing if the dots begin to disappear. Failing this either replace the toner and request a replacement from your retailer.

Incoming fax does not print, and also cannot get printout of faxes received. Memory was received. Regular printing and photocopying works fine.

if you found the msg on lcd like "toner empty" & red light near the lcd
then you have to reset toner counter through tech mode.
MENU # 1 9 3 4 MENU pres continues you will find tech mode on lcd
then press 3 times right arrow key "new cartridge" will come on lcd bottom line
then press 2 times ENTER button & swicth of the macine for 5 second then on

all samsung mfds stop printing FAX when "TONER EMPTY" msg comes.
