HP Officejet Pro 6970 problems / page interruptions & colour red/blue issues

[Liese1]

Hi ,

I have issues with a PDF document (34 pages).

Problem No 1)

The printer is stopping / interrupting th epage print on i.e. page 2 of a 4 page printing job.

Blank page following the interrupted page.

Its wasting pages and my instant ink page counter is counting down....

That is far from sustainable...

Problem 2)

A blue banner appearing on the PDF is streaking to red. Although a test page shows good results and cartridge ink levels a at minimum 30%.

Any ideas?

Regards,
Joerg

A new issue came up.

I want to solve this 1st.

       Testpage 1 from Print doctor (HP software) shows problems with blue & black color bars at the light end.

       Testpage 2 from the printer has no such 'light color' indication and the Page looks fine.

       Testpage 3 from the network printer page shows dark to light tapered colour bars with ALL FINE!!

(if this forum would allow picture upload I can scan all these print outs here and show them)

This seems a driver/software issue isn't it???

My printer is wireless connected and reachable via local IP address.

4 year old printer.

Hi,

How is a normal print from the PC?

Did you try a Word or a PDF print or any JPEG or PNG Image printing in color and black both?

How did they print?

This could be due to clogged Printheads on the cartridges or due to low on ink cartridges.

1) Please check the Ink Level of the Cartridges to ensure they are all proper and have ink.

On the Printer display, on the Home Screen, touch or swipe down the tab at the top of the screen to open the
Dashboard, and then touch (Ink) to check the estimated ink levels.

Any ink which is too low or Out of Ink, need to be replaced.

2) Clean the Copper Contacts on the Ink Cartridges.

While the unit is On, take the cartridges out one at a time.

Place the cartridge on a paper towel which you may discard later.

Observe the Golden contacts on the printer.

Clean the copper contacts using lint free cloth and clear water.

3) Do an Automated Cleaning.

On the Printer Home Screen, Click on the Set Up Icon > Printer Maintenance > Clean the Printhead > Continue.

Again go to Set Up Icon > Printer Maintenance > Clean Smear> Let it complete.

Now try printing and copying and check the results.

Ok,

the blue ink channels are clean.

1) I pulled all ink cartridges.

2) I interrupted the power supply so the print head stays in the middle

3) I moved the print head to the left and put a tissue (lint free below)

4) I covered all colours except the blue and blew in (through a tissue piece to reduce the air speed) with a contact cleaner spray.

5) I had released blue ink on my tissue- so the ink channels seem to be free.

6) I removed all tissues which I used to cover the 'good' colours and removed the tissue below printer head. Then I installed all cartridges, moved the head into the standard position for cartridge change and switched the printer on.

7) Next cleaning procedure of printhead shows again NO BLUE colour. So it seems it is an electronic issue.
