Yellow & Magenta not printing

There are several reasons why your Konica Minolta C250i printer may be printing magenta as yellow. Here are some troubleshooting steps you can try:

1. Check the magenta toner cartridge: Make sure that the magenta toner cartridge is properly installed and has enough toner. If the toner cartridge is low or empty, replace it with a new one.
2. Clean the printer heads: Use the printer's cleaning function to clean the printer heads. This can help remove any clogs or buildup that may be preventing the magenta ink from flowing properly.
3. Check the printer settings: Check the printer settings to make sure that the correct paper type and color settings are selected. If the printer is set to print in grayscale or black and white mode, it may not use the magenta ink.
4. Perform a firmware update: Make sure that your printer has the latest firmware installed. Sometimes firmware updates can fix issues with printing quality.
5. Contact Konica Minolta support: If none of the above steps solve the issue, you may need to contact Konica Minolta support for further assistance. They may be able to diagnose the issue remotely or send a technician to your location.

I hope these steps help you resolve the issue.

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.

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.

Tri color cartridge contains Cyan,Magenta & Yellow color inks, mono cartridge contain black ink, combination/mixing with these inks desired color out put will prints on paper.. If any one or more inks are missing/dried, result mis matched print outs on paper.
In your case I feel it's Magenta ink is not firing..,nozzles may clogged, try to clean the nozzles with solvents & try it...If no result ,. replace the color cartridge..

Ink levels are an estimate. They are approximated according to how much color might have been used. You may be out of all the color inks, they may be dried out or clogged. There should be a head cleaning operation for the printer, but it uses ink too.

Perform "clean print heads" in printer properties select printing preferences,service then click clean nozzles, perform twice or thrice then do the nozzle test, if print heads are recovered your will be in safe, other wise***Two print heads are in this printer each print head leads two colors, left print head leads black & yellow and other one leads cyan & magenta. You need to replace the print heads based on the color which missed.

This printer having four cartridges and two print heads.Each print head having two pens, black, yellow & magenta,cyan. As you said yellow & black are OK.. So replace Magenta & Cyan print head..

This model printer has only two slots for ink cartridges. One is for a black ink cartrigde and the other is for a tri-color cartridge which contains cyan, magenta and yellow inks.
This tri-color cartridge has run out of yellow ink, you need to replace this tri-color cartridge.

Dirty laser unit - needs (careful) cleaning internally.

See ' Printing Weak Magenta', 'Printing Light Magenta' for HP CM1015, HP Color Laserjet 1600, 2600, 2605.

All the same laser unit

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.
