Where is the ink cartridge? I need to replace it and I have no manuel

It uses cartridges, to change ink cartridge open from the section where the paper comes out from, take a good look you would find a small groove where your finger can enter then pull. while it is ON the ink carrier moves to the convienient position.

Try to re-seat the cartridges into the printer. Remove both cartrdiges > . pull out the power supply (black box where the power cord is plugged in at the back of the printer) and put it back after 30 seconds > firmly re-insert the cartridges. Let it print the alignment page.

If the display screen shows "low black ink" again, then try to replace the black cartridge. The printer requires all cartridges to have sufficient ink in them to continue printing. Try to replace your black ink with a new one, preferably a genuine cartridge.
Should you still need assistance, please leave a comment to my response and I'll get back to you.

you can usually open the front of your printer and just pull out the cartridges, they will snap out, just replace in the same direction as you took out. You could do one at a time so you won't get mixed up as to where they go. You can also go online and download your printer manuel, just look for the model and make and you should get one online. Hope this helps.

please put on the printer, open the lid, the ink tray will slide out, kindly replace as you remove, and ensure you have the recommended inks,

regards

Put offthe printer and manually pull the carriage to the position. Then the inks can be replaced.

You might have selected the wrong profile for your preferences. Go to printer properties and select defaults for all. This will solve your problem. If still facing problem comment back.
