ISO/IEC 19752 and EcoPrint switched off the toner container can print as follows (A4/Letter paper is assumed):
P-3521 MFP
Life of the Toner Container (Printable pages)
3,000 images
P-4020 MFP/P-4025w MFP
Life of the Toner Container (Printable pages)
7,200 images
• The average number of images that can be printed with the toner containers provided with the machine is as
follows.
For P-3521 MFP: 1,000 images
For P-4020 MFP/P-4025w MFP: 3,600 images
• To maintain quality, we recommend using genuine own brand toner containers, which must pass numerous quality
inspections.
Do not attempt to incinerate parts which contain toner. Dangerous sparks may cause burns.
