How to Initial Fill Your Printer

An Initial Fill Cycle is necessary for flushing all channels simultaneously when changing inks, or when installing PiezoFlush for cleaning or long-term storage, and especially so when trying to clear internal clogs from printheads and ink exchange units.

Why do you have to use the Initial Fill instead of running 20-30 Power Cleans or Powerful Paired Cleanings? To move PiezoFlush to your clogged head with that many cleaning cycles will burn out that ink channel and may affect adjacent channels. You can not do that without causing harm to the printhead. You should never run more than 2-3 Power Cleans in a row. They use electrical stimulus to the head and are not intended to be used one after another. The INITIAL FILL is the only procedure that uses suction alone. Yes, it wastes ink in all the positions, but it will not damage or delaminate your print head. That photo of the LK channel with the swath through it is what a delamination looks like during a nozzle test. If you are struggling with a clog, do not allow this to happen. If it has, an 11 ink color printer can be converted for use with Piezography. But to continue printing in color you will need replace the print head.

Before doing an Initial Fill Cycle, make sure 1. all cartridges contain enough ink or flush to avoid running empty (they should be at least 30% full or the sequence may fail mid-cycle), and 2. you have a spare waste tank on hand (or, even better: reuse and reset your waste tank). Note: the R3000 and P600s do not have removable waste ink tanks (all other printers listed on this page do), but an external waste ink bottle can be attached to divert waste ink to a bottle, which can be emptied as needed (instead of waste ink going into the bottom of the printer, which requires the pads be replaced by a service tech), and waste tank sensor reset using the Windows Epson Adjustment Program or Mac Waste Pad Reset (WIC Reset) Program.

IMPORTANT: The Initial Fill Cycle is performed using software or LCD panel instructions that EPSON field service repair people use and therefore no warnings are given if there is not enough room in the maintenance tank or the cartridges are not full enough. Repair persons know to check on this first which obviates the need for a warning! It is important less you end up with PiezoFlush leaking out of your maintenance tank or the sequence stopping before complete because of the detection part way through of a low ink supply as recorded on the cartridge's chip.
