Replacing the Belt Unit Recommendation for Replacing the Belt Unit When the belt unit nears the end of its lifespan, the message [Time to Replace Belt] will appear on the control panel to notify you that it is time to prepare a new belt unit. You can continue printing until the message [Replace Belt] appears, then printing will stop. The belt unit is recommended to be replaced after about 80,000 prints on A4-sized paper (single-sided printing). However, this page yield is for common printing conditions (3 pages at a time). Printing one page at a time can reduce the belt life by half. Memo • After the message [Time to Replace Belt] appears, you can print approximately 1000 more pages before the message [Replace Belt] appears. (When printing on A4 paper, singlesided printing, and printing three pages at a time.) Note • Even after the message [Replace Belt] appears, you may still be able to print by opening and closing the top cover. However, we recommend replacing the belt unit as soon as possible. - 62 -
