thank you for the video

Hello

you mean hair dryer is not hot enough ?

is this appropriate

TEMP RANGE	460 - 600 ºC

[Detonation]

Clogged printheads are usually the result of dirt/dust in the printhead. Heating it won't help that. Heating it to 450 ºC will for sure destroy the print head.

1: Fit new printhead wiper
2: run head purge

If problem persists carry out advanced procedure as set out below:

Press UP and OK to go to the Service Tools menu
Press UP and DOWN to go to Service Menu
Scroll down to Head Adjust, press OK
Set value to 255, press OK
Press the BACK button to return to the Service Menu
Scroll UP to Test Prints, press OK
Scroll down to Solid Fills, press OK
Select the colour that has the missing jets and print 20 solid fills.
Press the BACK button twice to return to the Service Menu
Scroll down to Head Adjust, press OK
Set value to 128, press OK.
Press the BACK button twice to return to the Main Menu
Scroll down to Troubleshooting, press OK
Scroll down to Print Quality Problems, press OK
Scroll down to Eliminate Light Stripes, press OK
Scroll down to Advance, press OK
Select the colour and jet number of the missing jet, press O


If that doesn't work you indeed need printhead replacement, will be cheaper to buy a new machine (not the same as CQ discontinued now) or you can buy a faulty 8570/8870/8580/8880 from ebay and use the printhead (all use same printhead)

You can get service manual by googling, comes in PDF form and details printhead replacement, takes me about 10 minutes but allow half an hour if you've never done anything like this before.

93-982 to 93-985 errors mean ink load obstruction faults for black,magenta,cyan and yellow.
As result the BK M C and Y reservoirs not filled.
There are a long list of checkings need to be done for managed this error.
So , if you want to continue, get service manual and follow the proper procedures described there.

Hello

a trained technician advised me to put it in an oven , i need to know if i can do something about it or order a new printhead from ebay

please advice

You've killed the printhead.

Not sure where you are, I should have some print heads available still. But I'm based in Europe, so better buy on eBay if you live outside of Europe.
