How is it possible that my mp190 printer does not print on photopaper

Have you set in your softwRe the size you want to print, since it standard often is set to a4, just change it under options

Adobe Illustrator expands the print dialogue box to include all sorts of prepress options.

Doing this removes the plain paper option.

If you set Plain paper with Greyscale printing, only the black Pigment tank is used.
If you set any other paper type, only the 4 Dye tanks are used - even if set to Greyscale.

hai there...you try press the reset and colour button in the same time...the printer will back to normallyl

I'm going to ask the obvious question here. Are you putting the paper in with the right side up?
I haven't got any similar paper here at the moment but I do know that many glossy photopapers look 'glossier' on the back than on the front.
The back is generally impervious and so the ink just sits in its little spheres on the surface and evenutally dries out to a fine powder - the soot you see on your fingers.
If that is not the case post a reply and let's think about other possibilities.

Firstly are you using the cirrect cartridge ( genuine)? some compatible ones have less drying agent to help prevent clogging but take longer to dry.

Some papers are not suitable to laser printers, so ensure the paper you are using is recommended for use in a laser. This includes Photopaper

Replace pick up rollers

Try removing all ink bins except black then you won't have any problems. You should also be able to go into your printer settings and select "Black and White" or "No Color" and it will print ok. Removing the ink trays is the easiest way though.

In the printer settings choose the type of paper, card, or the various photo papers that are listed. This must be selected to get the best quality for each project you are doing weather it is just normal text or quality photos, the both require different print settings. Usually by using the automatic setting does handle most settings but dont bank on it.
