Hello Landscapeman ,

You need to specify the paper type when the print dialog box appears. Heavy glossy paper needs to spend more time in the fuser so that the toner is fixed.

My HP Designjet T790 report "Error 21.2.:13, restart, if problem persists call support" i restarted but still can't print. Can you help me? Thanks


This is a service station error. One of the more common causes I have come across is a piece of paper or foreign object jammed in the service station. It is located on the right hand side of the carriage. Unplug the plotter. Plug it in and the minute that you hear the print head move, unplug the power. Then open the window, move the head out of the way and look for a foreign object stuck in the service station.

Cyan and Magenta does not print on the right side of the paper. Toner indicator shows three quarter of the cartridge to be full. Yellow and black prints are perfect.


I have worked/ serviced similar Laserjet Color Printer with same issue.
Actually, prints with faded colors or different colors are due the the dust/ toner dust accumulated on the optics (mirrors and lenses) inside the printer, which refect the laser beams to form prints. For instance, red color is formed by a mix of yellow and magenta toners. The color is replaced by yellow due the the partial or complete blocking of the image laser beam for
magenta as the mirrors which reflect laser beam get covered with dust and toner (which partially blocks the laser beams). Hence the image is not produced properly. This needs professional hands for servicing and cleaning of the optics inside the printer. Note that first magenta goes off, followed by yellow, then cyan and lastly black. This is due to the mirrors placement inside the printer. Magenta is the last one facing upwards at 45 degrees angle and gets most of the dust and goes off first.

Rest assure that the printer requires ONLY CLEANING OF THE MIRRORS, which are inside the printer. So, it is advised that you get the printer serviced by any printer repair/ service professional. (Please note that the mirrors, lenses and scanner assembly inside such printers is extremely complex and can get damaged very easily especially the mirrors).

Hope it would help. If you need any clarification, let me know
Good Luck!

HP Photosmart 3210xi - some colors (magentas) will not print


Remove the magenta cartridge, and try cleaning the head with alcohol, maybe with a small paint brush or an acid brush. It sounds like ink has dried and plugged up that head.
