*1 The recommended average print volume estimate for optimum device performance after factoring supplies replacement intervals and device life.

*2 Complies with ISO-9296.

*3 According to IEC/ISO 19752 yield measurements. Yield may vary depending on printing variables and conditions including toner and page coverage, continuous or intermittent.

*4 The stated page yield is a reference only and is based upon data taken from Epson’s internal testing under Best-Case-Scenario conditions. Various factors, such as intermittent print (with a few pages per job), paper size, paper direction, thick paper printing, print image ratio, frequency of shifts to power saving mode, frequent turning on and off of the power switch, will have an effect on the page yield. As such, the printable pages of consumables might decrease to half or less as a result of the printing conditions and printing environment.

*5 Maintenance Unit consists of 1 Fuser Unit and 1 Transfer Roll Unit.
