I read somewhere that if the printer receives instruction from the PC that it requires black only printing (e.g. a letter in Word) then it will use the 5PGBK tank. The 8BK tank is used with the other colours in photo printing only. If you check the greyscale option, it will use ink from the 8BK tank and mix with the CMY colours to print, but I have not tried this out.
Good luck

carefully remove the tanks from the print head cartridge. use a q-tip lightly soaked in isopropyl alcohol, or use a q-tip paired with an alcohol prep pad from a first aid kit.

gently rub the rubber seating areas for each tank, removing the dried ink from the rubber seat. swab the soaked q-tip, or use the q-tip to gently press the alcohol prep pad into the rubber stopper. use a different spot on the q-tip or pad for each one.

check the print head for ink stains on the black plastic, clean those as well.

Use canned air to dry the stoppers, replace the tanks, and check status. Print a test page and check results.

If you do not print many items, you can avoid the situation by printing a test page every once in a while to keep the contacts clear. Also, run the program to clean the print heads occasionally, and always turn the printer power off at the printer (that seats the tanks down on the stopper, helping to prevent the contact getting plugged by dry ink.

When you replace your inks with genuine ones, your printer will automatically recognise these and reset your ink levels.

Same problem, it seems that if you the original tanks, the microchip will block the tank after a number of prints. I guess there is no other solution than to buy new ones, without the limitation of the original tanks. This sucks :(
