why is printer printing black shades all over the pages

My printer ricoh sp 100 has all of a sudden started printing black lines actually all black shades. How to fixthis pproblem? ?

Just googled that printer and it's not a very good printer. Seems a lot of people have complaints about it.

Black lines like that are usually an indication of the issues with the toner cartridge and/or the roller mechanisms in the printer itself. Swap the toner cartridge with a brand new one, not a refurbished or refiled one to see if the problem is still occurs.

Where I work now the office printers regularly show these kinds of problems due to cheap refilled toner cartridges.

Interesting link on printer problems, I would avoid touching the drum like they show, skin oils won't be good for the drum's function.

I'm not familar with that machine but the problem can be due to a fault in the corona wire voltage or because something has contaminated the drum. Most printers have some method of cleaning the corona wire, often a built-in tiny brush that you can swipe from side to side. check the manual and see if it has one.

@ads-ee--- I saw that video before but the problem is the cartridges are different i mean its totally different every thing is compact, prints were fairly nice before it started.
@betwixt--- it happens that the cleaning brush is kind of inaccessible wait let me upload a pic

I'm assuming your's is the one on the left with the "handle" and a barely visible drum?

Was it a new cartridge or a refurbished unit?
There are some interesting issues with the cartridge refurbish market, like not actually doing anything to a cartridge besides adding cheap toner. Some companies actually do something like take the cartridge apart and rebuild it replacing anything that is worn. Of course they aren't as cheap as an "ebay" refurb ;-)

Well, but what can I do now? I bought this printer like six months ago and it had a warranty seal in the place where you have to refill the toner , so I am not sure about warranty .

Are you running the first toner cartridge?
How many prints in total (there should be a software counter)?
Did you print any non-regular media that might have contaminated the printer?
Are you operating it under extreme climate conditions?

I have refilled it before like 3 months before

There is no counter in its "Monitor for SP100 ----"

yes actually I did try to print with the photo paper but it didn't end well, it didn't go inside the printer but it more than a month ago.

No, I am here in Mumbai


I did notice some smell around it something like a over heated Iron press, But it was printing fine then, that event occurred just before the day all black thing started coming out

Refilled two times means that the toner drum may be simply worn out.

Thanks FvM for your input.
The printer has somehow started to work again, one or two pages came out with descending black streaks but now its working fine 8-O :thinker:

HP2620 is an inkjet not a laser printer. You are observing a different problem, e.g. spoiled ink.

"The difference comes in the way the technologies adhere ink to the page. Inkjets spray ink onto the page through tiny nozzles, creating microscopic dots. Uncoated paper—everyday white paper—absorbs ink, which causes bleeding, blurring the edges of everyday text. Specialized photo paper can prevent the bleeds and control drying times, allowing for professional-quality color prints. However, everyday text will not look as sharp on an inkjet as on a laser because of the bleed factor.

Laser printers work by using high heat to fuse powdered ink to paper. There is no bleeding effect, because laser toner does not absorb into paper. Prints are smudge-proof, need no drying time, and rarely require specialized paper. However, the sharp, crisp edges from a laser don’t allow for the same subtle gradients of color that an inkjet can produce. Color lasers must lay down colors one at a time, and toner has a bit of opacity, unlike wet inkjet inks. Although color lasers aren’t the preferred choice for maximum photo-quality prints, they can produce speedy and crisp results with solid image quality and perfect text."

I must agree. When I am in doubt over somethings, Google is the best source for me.
