Streaky copies Ricoh FT 4215 copier (laying unused for 1 year) Printed 40 copies or so and output mainly black with horizontal and vertical streaks. Reduced to lightest copy setting and white appears gray and still darker vertical and horizontal streaks appeared.

if you are familiar with ilumina menu search for the ID Test Pattern. Print test using 11 x 17 page.
On the copy you will see which of the drums need to replace, if the copy has vertical or horizontal lines on it the drum which ever color shows it has to be replace.

Hi,

Are the Streak lines vertical or horizontal ? Most likely it could be due to Toner issue, Try to remove the toner and clean it and re-install it

Hi, Sounds like the yellow PCU is faulty, pressuming the streaks are vertically down the page.
If they are horizontally across the page it is probably another issue.

Are you getting these lines when copying? Or Printing?
Or both. Are these dark lines or blank lines?
If it is just when copying, try making a copy by laying an original on the glass rather than using the feeder. If this copy comes out clean then you need to clean the ADF (Automatic Document Feeder) scanner glass. Just open the section where the documents are fed into and you will see a strip of glass that runs from front to back, about an inch wide. Clean this with a soft cloth and a bit of glass cleaner.
If this works then great. If not then reply back with more details and I will help you further.

Clean the scanner strip glass. This is the small strip of glass that is just to the left of the large main glass. This is the only cause for black line (s) when copying using the ADF(top feed). If prints or copies fine from the glass then it is this strip glass needing to be cleaned.

A) Black Streaks, Shadows, And Ghosting
Adjust the printer's lightness/darkness setting to 2-3 different variables and see if problem disappears. Look at the fusing assembly - is the roller torn or does it have any black buildup? Use caution!!! It gets HOT!

Try another toner also.

I was going crazy! Had a tech come in and look at the machine - needless to say he did NOTHING! A friend came over and was trying different things. It was that the "rack" that the toner cartridges sit in was not fully seated - once he pushed down a little and heard it "click" I had no more black streaks. AMAZING

HI,
I think you should change your printers tonner.

Thanks

if you need any parts for that machine a have 4of them

Thank You,

Mikey
