Cyan Brings Dirty Background on Copy-IRADV 5045

[Andyboachie]

Hello,
I worked on an Ir5045. It was bringing clean copies, just that it was due for servicing. After I did a very thorough cleaning, The copy for both printing and copying appear with cyan creating dirty background. Please find some attached copies. I really count on your kind suggestions.
I changed the cyan dev unit and the drum unit. And as I said above, I did a very thorough cleaning, so the laser and other lenses can be overlooked. I tried going through its service manual, but I haven't chanced on a probable solution.
Thanks in advance

You did not solve blue background
with new developer and drum?
Any changes if you put back old drum and dev.?
OEM parts?
Probably you make mess on blue laser unit.
Please post a PG-10 test.

Are you a copier tech?

Did you run all the necessary calibrations after replacing drum & DV?

OEM parts or aftermarket?

If it was working fine before you changed the DR and DV, try putting the old ones back in to see if that corrects the problem. If so, you have a problem with the drum or DV. Or both.

When you did a 'very thorough cleaning' what exactly did you clean!?

Totally incorrect, this model does not a have a 'blue' laser unit 'mess' on the laser unit would give faint copies/prints not cyan background.

This model HAS a blue laser! Two laser units. Each unit is for two colors. And if you didn't know a badly connected laser can cause lines of the same color in the background or error 100.
I still doubt he has a laser problem.

Am I wrong or are you making fun of my English?

Its a cyan laser, not blue.

I agree with copier tech. Spilling toner on the laser slit glass isn't gonna cause a "blue" background. It's gonna cause a faint image.

You didn't use new oem drum and dev assy replace parts that are needed take out and clean lasers and setup correctly or call a credited service engineer if you haven't been trained

Looks like drum charge contact issue, swap cyan and yellow drums with each other.

Hello Guys,
I'm so grateful for the useful comments you made. Yes I'm copier tech for 21 years. It just occurred as a faulty board on the Black/Cyan laser. There was a break behind the port housing the steel connect. It caused shortage to cause that problem. Instead of replacing the whole laser unit, I chose to replace the board alone on the faulty laser to be sure. It worked perfectly.
Once again thank y'all for your kind suggestions!
