How to clean leftmost side of LaserJet 4L printer?

Every page I print on my HP LaserJet 4L is dirtied with a 1/8" grey smudge of toner on the leftmost side. (It's like a grey margin on every page.) I have spent over an hour hunting around the HP website for instructions on how to clean the inside of my printer to remove this. I cannot find any diagram showing the inside of the 4L, where to clean, how to clean, etc. Can someone please help me?!

Hello, D. Steppel,

It sounds like a repetitive defect. See the following.

http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=bpl10515#N10621

I couldn't locate a document on cleaning for the 4L. These are diagrams on the unit (dropdown menu).

http://h20141.www2.hp.com/hpparts/search_Product.asp?mscssid=1NL2DR6QP16G8MS8S8CACBQXGFBW6LW1&Search...

I'm not sure this will come close to the 4L unit - 5/5M doc

D. Steppel,
The problem is most likely the toner cartridge.
There is a cleaning blade on the inside that removes the excess toner from the drum.
These cleaning blades tend to wear on the edges.
Take the cartridge out and raise the flap that covers the drum if you see toner on the drum which is the same side as the print outs then it is time for a new cartridge.
If it is not the drum then canned air will help in removing and excess toner from inside the printer.
Too much of everything is just enough

John Hutchison hit the nail on the head.
The printer itself didn't need cleaning;
once I replaced the toner cartridge (which
needed replacing anyway), the problem completely disappeared with the first test print. Thank you very much!

Pat, nice try, but I think I was leading you
down the wrong path. Plus, the first website you referred me to sent me to "find the owners manual," and I have been unable to locate the manual online (and my paper copy disappeared multiple moves ago...this printer is almost 13 years old). Thanks for trying, though.

Re: How to clean leftmost side of LaserJet 4L printer?

You can order the 4L Service Manual - Part Number C3980-91078

The User's Guide has been discontinued.

http://h10025.www1.hp.com/ewfrf/wc/genericDocument?cc=us&docname=bpl03756&lc=en

Some cd-roms contain the User's Guide

Should you need the diagrams available, type Laserjet 4L in model number, click on model number and you'll see a diagram dropdown menu on the following page.

Re: How to clean leftmost side of LaserJet 4L printer?

Two additional things to check:

1.Make sure you ink carteadge has the ink evenly distributed in it. You can do this by taking the cartidge out, hold level and sheck it from side to side.

2.Make sure the mirrow under the top lip of the ink cartridge receptacle is clean. You may be able to clean it with a soft white ragwithout removing the top cover of the printer. It is worth a try, even if you do have to remove the top cover to get to the mirrow.
