Epson 4000 WART.ERF. 0040 - Epson Stylus Pro 4800 InkJet Printer

Did you replace the low ink cartridges? The 0040 request code is from the ink dispenser pump saying it has reached the specific number of pumps for that particular ink cartridge. Once you change out the low ink cartridge the pump will automatically reset.

See images below

You probably need a maintenance kit. It consists of new ink waste pads, a purge unit, and some other little parts. Contact Epson support

Use the above link or send an email to [email protected] and I will send you the manual. Please put "Epson 9800" as the subject.

Maintenance request code:

The pump counter is near end of life, replace the cleaner kit ASAP.

This is what 0040 means.

While powering up the printer, hold down the three leftmost
arrow buttons:
[left-arrow] [down-arrow] [up-arrow]

You will get a whole different set of menus.
Use the up/down arrow buttons to select the "Clear Counters" menu, then press the [right-arrow] button.
Use the up/down arrows to get to the maintenance tank entry... where you can clear its counter.

Then turn the power off, wait, then turn it on.

You can use this diagnostic startup to clear most of the counters (and their related maintenance codes).

The ERF 2030 will not work with out the added companion parts that need to be added with!! I am assuming you had all the parts with the ERF 2030 and instructions??

The added parts are as follows: along with the ERF 2030
1-EN 1230 & 1- pF Ceramic disk capacitor

aha and your printer is not functioning right now isnt it, or it is still operational, either way that error must be solve or you will never use your printer. this error means that your pump motor is near end about 5% of its life is left. here is the sure solution for your prob. turn off your printer then press the left, down arrow and enter simultaneously then power on the printer. inside initialize the sponge and cleaner then turn off and on your printer. note: you will have to replace your pump cap assy. if it is already poor in cleaning otherwise your printhead will suffer.
