Question about Sharp FO 4450 Laser Fax

1 Answer

Poor Print quality - black lines appear on page

I am getting black lines accross the entire page on a received fax. I have about 12,000 copies on the existing drum. If I look at the drum there appears to be the black lines embedded on the drum. Is it time to change the drum? I did not get a warning from the fax itself stating the life of the drum is nearing the end.

If you see black lines on the drum, it is very likely that the drum unit is bad. Replace the drum unit and rest the drum counter. If you wait too long, you will cause toner build up in the fuser and will cost yourself several hundred dollars to get it replaced. More in labor than parts.

Use a soft cotton or very soft paper towel and wipe the excess toner from the drun. If there are lines worn in the surface of the drum, then replace it ASAP.

2" black horizontal line appears on paper when I fax, print,


Check the wondow where the paper passes to be scanned. You will probably find some debris or white out stuck on the glass. That is usually the cause of vertical lines on sent faxes.

Distorted copy quality in the sent faxes


Make sure the rollers that pull the paper through are clean and that the glass is also clean. Clean the rollers with a cloth dampened with alcohol.

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.

Error 441*


Error #441 is caused by poor line quality accross the telephone line or faxing to a non-compatible fax. Try faxing to someone else as a test, if it still happens, try moving the fax to a different phone jack. You can also try faxing at a differn't time. Also try replacing the phone cord attached to the fax.

In all cases it's either phone line, phone cord or non-compatible machines (old fax on receiving side).

The machine told you poor line quality. Try a different phone line to verify. Try it at a friends house to verify it. If you are using Vonage, that is the problem. I have Vonage and every fax I test with has some issues with poor line.

Poor Quality


If you can copy ok you have effectively ruled out your machine as you have used both the scanning and printing mechanism of the machine.

It will probably be the fax on the other end as if it sends a poor quality page that's all your machine can receive, a poor line can also cause problems if it is from multiple faxes. If so have your provider check the line (you probably hear static on the line).
