Blurred officejet 4620 photo

dear clean the platen glass and its cover. adjust the sharpness.darkness.image quality to text and photo.
your printer is in good condition.
thanks.

usually, if not all almost all printers allow you to set printing preferences before you print.
1. In windows, when you are about to print a document or photo, click preferences then you should be able to change printing quality. Usually, printers have radio buttons(option

buttons to select best "text","best quality", "photo quality" and "best photo quality". Just selct your preferences then click ok, then print.
2. If printing photos, there will be a warning to use photo paper instead of the usual paper.
3. Did this answer your question?

Check into the PRINT settings, available when you print a document. The paper type invokes different inks and print quality.

Maybe the print quality if set to text print quality, change it to photo print quality to get print quality.

Go into the menu and find picture quality..set it to extra fine.

you shoud test printhead,if they are ok, you choose "best photo" in printer property.

You want to set the focus mode to S-AF, then move the focus mode selector to the lock position.
Hopefully that will fix the problem.

there are 3 reason if the copy gray & less sharp:
1) the toner you are using is not compatible very well with the cartridge unit if you changed other compatible toner.
2) the cartridge going near the life-cycle, (also cause print blurred)
3) the photo drum going near the life-cycle
you may try to change the quality toner (original factory). or
change the cartridge if it is out of the life-cycle

Make sure that your quality is set to best and you are using a high quality photo paper for maximum resolution and quality.

Click Start - All programs - HP - HP Solution center.

In HP solution center Click on the Printing Shortcuts tab. Select Photoprinting with borders or borderless. Click OK.
Then close the HP solution center. Try printing. Print photos always with Best quality.

If the issue persists check the ink level of both cartridges and use Photos Cartridge HP 58 to print photos. We insert the Photo cartridge in place of black cartridge.

Thanks
