New print heads are a stupendous 1200$
Cleaning solution is 25$
New ink set 200-250$
A friend and I want to attempt to clean this thing up or convert it to black and white only. His ambition is simple party banners he uses a company machine for now but would be convenient it if was around the neighborhood instead.
Me... well I just want to mess with this huge printer!
Any suggestions, tips, or mods we should consider!?
It’s free except for the gas to get it. We don’t mind trying risky solutions!
Or just say we are crazy!
If he is already using refillable carts that saves lots of money. A friend discovered these dye inks available for color printing from Piezography, that are not so lightfast, end up being a good solvent/cleaner to restore a clogged 3880 he bought for no money.
With clogged heads "time is your friend" so just let the solvent work over time.
Also repeated power cleaning without ink flow can overheat a head and damage it.
For more free advice the Piezography website has a forum for ink jet printers.
In my case I bought a gallon of Piezoflush and a set of refillable carts to restore a decade old 7800. My printer was not totally clogged, but needed some TLC and maintenance.
Are you aware that the carts are about 350ml and that I don't think $25.00 for solvent is correct/right. Paid about $550.00 for a set of carts and a gallon of Piezoflush. This is the way to go for B&W.
For color I'd use the dye inks to save money, even if just for storage or cleaning.
As far as durability the 7900 were not known for their long print head life, while the 7800 and 7880 are known to be workhorses with exceptionally long print head life.
I will warn you that a 24 inch printer likes to be used and that using one is not inexpensive. Paper and ink gets really costly. A roll of 24 inch wide costs about $200 or so and you only get about 15 24x36 inch prints. Works out to be about $15.00 in paper alone for a 24x36.
Good thing is roll paper cost less than cut sheets. Running 17 inch rolls will save you about $1.00 a print over 17x22 cut sheet. Figure $5.00 instead of $6.00 per print and saving a dollar per print. The big printers also have better paper handling/transport.
When I run my 7800 I have to top up the carts every few weeks, and to save money I bulk up on 700 bottles that I literally use a small funnel pouring ink.
