- Epson 1400 with carbon inks
My first post was about getting the T511 cart open.
I was able to collect all "Epson Archival Ink" Black Ink from within. This is a beautiful warm tone ink, mostly carbon, enough to print for a long time.
I'm converting an Epson 4900 that was headed to the dump to a B&W printer. K channel seems dead.
I ordered refillable ARC carts, made up C6a base and diluted this ink into 2%, 6%, 9%, 18% and 30%.
I decided to use the left side of the printer (6 carts) for the entire inkset and undiluted ink was placed into the OR cart.
1 initial charge down the road (for the left side only) and I had all diluted inks working properly, but the undiluted ink was brighter than 30%, it has some dark spots, but it is mostly banding throughout the entire %s - using QTR's inkseparation file. Beautiful nozzle check nonetheless.
I introduced 5% base into the 100% cart, turned it over a couple times and did one more initial charge. No change.
Introduced another 15%, making it 20% C6a base, then I didn't have space for another initial charge (resetter is somewhere between China and Brazil), so I printed around 20 A4 full area purging OR channel using the appropriate file from QTR. One manual clean of both GR and OR. 7 or 8 nozzle checks all perfect. Still no change in banding.
Air bubbles in OR nozzle?
OR nozzle bad for K ink?
Bad damper? Should change the channel?
