How do I remove ink cartridges that still contain ink in DX 7450

Remove the cartridges and do a full reset without them in by removing the wall socket and re-plugging.

You copier does not use ink, but toner. And because the "ink" detector is on, it could be the toner cartridge is empty.
Try to remove the toner cartridge and shake it firmly. than replace it. This could help for a few copies, but you must order new toner, if the sheets of paper keep coming up blank.

First things first... try connecting your printer to another pc or laptop and try printing... make sure spooling is on in the driver and there are no other programs running...

if issue reappears then

It sounds like your printer cartridges are the issue

I would try reinstalling them...

if that does not work then

I would try cleaning your printer cartridge...

Gather cleaning supplies:
Clean distilled water. Use bottled or filtered water if distilled water is not available.
Clean cotton swabs or any soft, lint-free material (coffee filters work well).
Remove both cartridges.
Unplug the printer.
Lightly moisten the lint-free cleaning material with clean water.
Clean the cartridge contacts. Avoid touching the nozzles. Replace the cleaning material if it gets dirty.

If that does not work then I would try ordering some new cartridges

Although you are only trying to print a B & W picture, the color print cartridge/cartridges must also contain ink in order for the printer to work. All print cartridges must contain ink for printing of any type to take place.
Load the color print cartridges and the B & W picture will print.
If you were trying to print a color picture and the B & W cartridge was empty, the printer also, would not print.
I hope this helps you out.
Good Luck

Activate epson status monitor, if ink reach ink out, the message will appear. Then follow "How to..." Manually, turn on printer, and unplug power while carriage moving. Then move carriage by hand to replacement position. Replace ink tank, turn on printer.

NO

It sounds like a driver issue. Have you checked that bothcomputers have the correct driver for your printer?

I have an Epson dx 7450 scanner printer that will not accept non epson so called compatibles .Anyone found a solution ? I've tried a number of manufactuers and they all don't work . I really don't want to fork out for epson inks ?

You must surely have sorted this one out by now Doris! However, if you haven't, how to change print cartridges on a DX7450 is very clearly explained in the user handbook (on the CD that came with your printer). Insert the CD and select "Custom Install" then "Users Guide". Once its installed, double click the new Epson Icon on your screen and selct "Printing" then "Replacing Ink Cartridges". If you don't have a CD, download the User's Guide from the Epson website at http://www.epson.com - just choose your locale, then select Get Drivers and Support - Printers.

switch on your printer then open the front cover the cartridge carrier will come and rest in the opening, just pull the cartridge and put the new cartridge
