I replace the ink on my fax 1860c brother

maybe the black ink damage, try to replace it by a new one.

I have a Canon Laser printer that is not wireless. I was getting ready to buy one because I need more desk space. I was glad to read this about the wireless print server. http://top10printers.com/

All ink jets mix all of the colors every time, even for black.

Don't you see the logic? Brother wants you to spend money by buying color cartridges. And also, most printers are also using colors to make the prints darker.

I'm afraid so. The color mixing process uses all of the inks all of the time.

You cannot have just black ink.

you probably will have to use the cleaning function on the machine a few times (4-5). the unit uses the color ink every time it prints or cycles

All i needed to do, after messing with it non stop, was turn it off and reboot the machine. Simple solution! Thank god!

It's all a scam. I have the same problem and I called Brother and they told me that the machine uses color ink to clean itself. It costs more to replace these color cartridges then to buy a new one, which is what I'm going to do. Buy a black and white from a different company. It's all a scam to get you to spend money on their color ink that you don't use.

Sadly in a word, 'No'.

Here is the exact answer from Brother:

Your Brother machine is designed to stop ALL printing operations
(printing from the pc, printing received faxes and printing copies or reports) when any of the ink cartridges are empty. This is to ensure the life of the print head and maintain premium print quality. If the unit were to continue printing, print jobs and cleaning cycles would suction air from the dry cartridge and damage the printhead. Even if you print in black only or change the print settings to MONO or GRAYSCALE to avoid printing in color, the programmed cleaning cycles would still suction the dry cartridge, because they are programmed to clean ALL the ink nozzles.

The only way to continue printing is to replace the empty ink cartridge or cartridges.

While memory is available, black and white faxes will continue to be received into memory. If a color fax is being received, the Brother machines HANDSHAKE will request the fax be sent as black and white fax.

All faxes received into memory will automatically print once the ink cartridge is replaced.

NOTE: Brother strongly recommends that customers do not use generic ink or refill their Brother ink cartridges. Using non-Brother supplies may affect the hardware performance, print quality and machine reliability since the ink formulation in genuine Brother ink cartridges prevent smearing and clogging of the print head. The Brother limited warranty does not apply to any problem that was caused by the use of unauthorized third party ink and/or cartridges.

Three reasons -

If your print driver is set to color. It will use all the colors to make black.

Because the machine is ink jet it needs to clean the print head to stop it from drying out. It will use color ink to flush the print head every two days.

When ever in receives a fax it will use some color when printing a fax, particularly Cyan.

If you only wish to print or receive faxes in black there is now a version of Brother fax that only uses black ink and has no color inks. However it may not be available in your region. If you try and cheat the system you will only kill your print head.
