The printer will not operate if a black ink cartridge is expended or any cartridge is removed. If a color cartridge is expended, you may be able to continue printing temporarily with black ink. It`s best to always have extra cartridges on hand.
There may be several reasons behind the issue, such as empty ink cartridges, Clogged Print Head Nozzles, and Incorrect Print Settings. There may be a fault in the settings of Color Management as well. You can fix it via Running a Nozzle Check or enabling the Print Settings to Color or Replacing the Ink Cartridges.
The Cause of Clogs
Printheads clog because nozzles get blocked by either air or ink. Clogs usually happen when: You keep printing with depleted ink cartridges. Using empty ink cartridges can result in air bubbles that can clog your cartridge and/or printhead.
Black Print Mode allows you to print only with black ink as a temporary emergency measure to minimise the down time in the event any colour inks are expended, even if there is no replacement cartridges available.
The quick answer is: Yes, you can (if you own a printer model that allows it) — but you shouldn`t keep printing with an empty cartridge for too long. Why? Because running on an empty cartridge for too long can cause your printhead to overheat resulting in irreversible printer damage.
Make sure the document is set to print in color and enable the color printing feature on your printer. Check the ink level and replace the ink cartridge if necessary. Clean the print head. Most printers have an automatic cleaning feature now.
If your PC or the LCD screen on your printer is telling you that your ink cartridges are full but no ink is passing through to the paper, then it`s most likely that you are dealing with a clogged printhead. Blurry documents and images that appear faded are also signs that it`s time to remove the excess ink.
Select Print Settings from the pop-up menu. Select plain papers or Envelope as the Media Type setting. Select the Grayscale check box. Click Print to close the Print dialog box.
Even if you select Black/Grayscale or Grayscale in the printer software, some color ink is still being used. Epson printers contain a permanent print head that needs to be charged with all colors to work. Even when you are printing black text only, a small amount of color ink is used to keep the print head charged.
If the printer is printing black only, the Ink option in the printer driver may be set to Black instead of Color or a setting in the software may be set to print black only. Also, the print head nozzles may be clogged.

Method 1 – Bypassng Ink Cartridge on Epson Printer
After opening the lid, hold the ink button down. When you find the ink holer is moving to its position, then open the cartridge`s lid which is having no ink. Close it again without removing the cartridge. Close the lid and start to print.
You can also tell which cartridge is empty by checking the speed at which the error light flashes when the print head moves to the ink cartridge replacement position. See the table below. Replace the black ink cartridge if the error light flashes at the same speed as the power light.

ANSWER : After Windows 98, Canon stopped supporting the BJC 70/80/85 series. Drivers were available for W98 and earlier, but now these are no longer carried on the Canon website. I now have my BJC 70 & 80 working, not only on a virtual machine running WinXP but also on the host which runs W8.1.In the case of Win XP it seems that a 3rd party driver was used, but I am mystified as to how it got onto the W8.1 machine, because I have a vivid recollection that the BJC managed to auto-install itself as soon as it was plugged into the USB port without any action by myself. I never expected it to work with Win8.1. I was resigned to using it only with the Virtual copy of WinXP, which meant that the printer needed to be connected only AFTER the virtual machine was booted. Now my little Bubble-Jets are accessible both from both the virtual client and the host. The most likely explanation is that I did actually find and download a 3rd party driver for Win8.1 and that I have had amnesia.
