LJ Enterprise 700 Color MFP M775f
Fax capability is the mark of the LJ Enterprise 700 Color MFP M775f: the complete wide-format document station, with every function — print, scan, copy and fax — working on A3 pages in a single machine. It runs HP 651A cartridges: black CE340A with cyan CE341A, yellow CE342A and magenta CE343A alongside.
Some departments never stopped faxing: signed authorizations, medical and legal paperwork, orders from customers whose systems still speak fax. For them the M775f removed a whole device from the floor — the standalone fax machine and its separate supplies — and folded that traffic into the big MFP they already fed. One machine, one cartridge family, and a document workflow that covers paper arriving from any direction.

Do not let the three-color set on this shelf steer an M775f order in the wrong direction. It is stocked here under the 651A name, yet the codes printed on it — CE261A, CE262A and CE263A — belong to a different HP cartridge family, not to this MFP. What the LaserJet Enterprise 700 Color MFP M775f actually uses is the CE340A series above; the safest check before ordering is the code on the spent cartridge you take out.
Which cartridge should you buy?
Split the machine's work in two. Everything arriving by fax, and most copying, prints in black — so the CE340A is the cartridge an M775f lives on, and the one to hold a spare of. Color cartridges serve the documents the department creates itself, and they go one at a time: replace the single flagged color and keep the others working. A four-color set earns its shelf space when several cartridges report low together, or as the reserve box for a machine that cannot be allowed to stop. All of the compatible cartridges here carry a 1-year warranty with 1-year returns.
Chip, toner and everyday use
A fax-equipped machine gives no warning holidays: a cartridge that empties overnight can mean faxes waiting in memory by morning. The practical routine is to act on the first low warning — order then, swap when the machine insists. Swapping itself is quick: the front door opens, the empty cartridge pulls straight out, the new one slides in to a click, and the machine calibrates and reads the new chip on its own. Keep cartridges in their sealed bags until that moment, stored flat in a cool spot, and give a fading cartridge a gentle rock to spread its remaining toner before you decide it is finished.
Frequently Asked Questions
Does receiving faxes use color toner on the M775f?
No. Incoming faxes print in black, so fax traffic draws on the CE340A alone. The color cartridges — CE341A, CE342A and CE343A — are spent by the printing and copying your own office does.
What toner does the M775f take?
The HP 651A set of four: CE340A black plus CE341A, CE342A and CE343A for cyan, yellow and magenta. Any listing carrying those exact codes is the right cartridge for this machine.
Can the M775f copy and scan as well as fax?
Yes. It is a multifunction unit — print, scan, copy and fax in one machine, with the scanner glass for single sheets and the document feeder for stacks. Scanning uses no toner; copying draws on the same four cartridges as printing.
How should spare toner be stored for a machine that can never stop?
Sealed, flat and indoors — unopened cartridges keep their full life in a cool, dry cabinet away from sunlight and heat. Break the seal only when a cartridge goes into the machine, and keep at least the black on hand at all times: on a fax line, the black cartridge is the one that cannot wait for a delivery.
