    6. Troubleshooting Click the [Power ON] + [Start]. • 4in1 Use the User Tool. Dark Lines in Halftone Areas Dark lines in halftone fill areas can appear at 75 mm intervals when the machine is operating in a room where the humidity is very low. (The low humidity causes variation in light sensitivity across the surface of the drum.) To prevent this problem, open Smart Organizing Monitor.

  • Page 211: Common Problems

    Common Problems Common Problems All Models Please remember that print yield will be different based on how the machine is used: • The rate of toner consumption is much faster with documents that consistently contain photos or charts that require large areas of fill. The AIO will run out of toner much sooner. •...

    6. Troubleshooting Refillable Printer, 3in1 Operators do not know when to change the AIO. Make sure the operators understand the following points about AIO replacement: • For the Refillable Printer, 3in1 the machine does not monitor the level of toner remaining in the AIO. There is no toner near-end or toner-end alert.

    7. Energy Saving Energy Save Energy Save Modes Energy Save Operation Operators should use the energy saver modes correctly in order to save energy and protect the environment. The shaded area in the diagram above represents the amount of energy that is saved when the energy save timers are operating.

  • Page 216: Timer Settings And Return To Standby Mode

    7. Energy Saving Timer Settings and Return to Standby Mode The operator can set the two timers with the Smart Organizing Monitor (Printer Configuration > System tab > Energy Saver Mode 1 or Mode 2). • Energy Save Mode 1 (30 sec.) can be only turned off or on. The length of the timer cannot be adjusted.

  • Page 217: Paper Save

    Paper Save Paper Save Effectiveness of Duplex/Combine Functions Duplexing and the combine functions reduce the amount of paper used. Far less energy overall is used for paper production and paper disposal. 1. Duplex Printing on both sides of each sheet of paper reduces paper consumption by half. 2.

  • Page 218: Total Counter

    7. Energy Saving To check paper consumption, look at the total counter and duplex counter. The total counter counts all pages printed: • The total counter increments by 2 for each duplex page • The total counter increments by 3 for two duplex sheets where only three pages are printed (one side is blank).
  • Page 219 Paper Save Original Simplex Sheets Duplex Sheets Paper Saved Total Counter If the combine mode is used, the total and duplex counters work in the same way as explained above. The following tables show paper savings and how the counters increment for some simple duplex/ combine jobs.
