Expected page output and replacement cycles
Page yields for Epson 138 ink cartridges are tested under the ISO/IEC 24711 standard for inkjet printing. Actual yield varies based on coverage, with high-density text documents depleting the C13T138192 Black cartridge faster than individual colour tanks during routine office printing.

Pro Tip
When replacing cartridges in a four-colour individual ink system like the WorkForce 840 or 845, keeping extra colour cartridges on hand prevents workflow halts when one colour depletes during automatic head cleaning cycles.
Frequently Asked Questions
Do the Epson WorkForce 840 and WorkForce 845 use the same ink cartridges?
Yes, both the Epson WorkForce 840 and WorkForce 845 share the exact same Epson 138 ink cartridge series (C13T138192 Black, C13T138292 Cyan, C13T138392 Magenta, and C13T138492 Yellow).
Why does my WorkForce printer stop printing when one colour cartridge is empty?
Epson WorkForce printers require functional cartridges in all four slots to protect the permanent MicroPiezo printhead nozzles from drying out or drawing in air during print jobs.
Can I replace individual ink cartridges on the WorkForce 840 and 845 as they run out?
Yes, the 138 series uses individual cartridges for each colour channel, allowing you to replace only the specific empty cartridge while keeping the remaining cartridges in service.
What happens if I print mainly in black and white?
Even when printing monochrome documents, small amounts of colour ink from the C13T138292, C13T138392, and C13T138492 cartridges are consumed during maintenance routines to keep the printhead firing evenly.
