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

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

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.

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

I have a similar problem  only I get very dark horizontal lines on the left side of the paper.  I'm assuming it's because some toner from a new cartridge fell into the machine.  I called HP (prob. an offsite guy from India.)  He wasn't much help, other than tell me to use ONLY a non-lint cloth or paper towel to wipe the toner off the front roller.  Have used an amazing amount of paper towel as well as some cutips.  And not much has changed.  

 

I think I downloaded a manual for the LaserJet 4 that showed some diagrams of where stuff was inside, but I'm not mechanical enough to tackle the logistics of how to figure the whole thing out.

 

(Here is address I went to to get some manual info)

https://ia801501.us.archive.org/32/items/printermanual-hp-laserjet-4l---4p-service-manual/hplaserjet...

 

Maybe start at page 51  (it's about toner cartiridges)

pg 53's instructions about rotating the cartridge back & forth to evenly distribute the toner  is what caused me to get all that toner into my machine.  (don't rotate it over the area you'll be inserting the cartridge, which is waht I unfortunately did:(

there are some diagrams of the machine starting at pg. 95 (of 306)

 

If you can figure this out & provide me with the solution to those side marks (what am I looking to clean for that?)

    I'd appreciate you posting it on this forum.

      Thanks.

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

if you do have a 4l, it is old, old old.

 

99% of image problems on printers come from two areas, the cartridge or the fusing assembly. How old is the cartridge? Print a page and you want to stop the machine while the paper is in the printer. yes causing a jam. You want to see if the defect is on the page before it goes to the fuser. If the defect is on the paper, look at the cartridge and see if there is a band going around the drum. if not look through the back of te machine and see if you can see anything wrong with the fuser.

 

it has been 10+ years since i even have seen one of these
