There are four remaining-toner states in this machine. This is almost the same as for the ProC751EX series.
Remaining-toner State | Descriptions |
|---|---|
1. Sufficient Toner | Sufficient toner exists in the toner cartridge. The amount is estimated from the pixel count executed during the cartridge life. |
2. Pre Toner Near-end | When the amount of toner estimated from the pixel count drops to a certain value (SP3110-011 to 014; Default = 10), the machine warns the user that the toner cartridge will be empty soon and a new one should be prepared. This function can be disabled with SP3-110-001. The default is '0: On'. This function enables an earlier notification before replacement is needed. ”Toner runs out soon. Prepare a toner bottle for replacement.” will be shown as a banner message. |
3. Toner Near-end | The toner end sensor could not detect toner arriving from the toner cartridge. Remaining toner (%) in the bottle is zero. But there is toner in the sub-hopper. 400 sheets (A4/5% chart) can be printed with this toner after toner near end occurs. Toner remains only in the sub hopper. ”The toner cartridge is empty. The machine will soon stop printing. Replace toner cartridge” is displayed as a banner message. You can replace the cartridge while the machine is operating. |
4. Toner End | Either 400 sheets was printed since toner near-end, or the estimated pixel count indicates toner end, whichever comes first. The machine stops and tells the user to replace the cartridge. |
Here is a flow diagram of the toner end / near-end states, with explanations.
Flow Diagram | Remarks | |
|---|---|---|
1. Toner Full | ||
2. Pre Toner Near-end | Prerequisite: Toner full Switch enabled/disabled In SP3110-001 [0:ON / 1:OFF] Set the threshold in SP3110-011~014 [Default: 10%] | |
3. Toner Near-end | Prerequisite: Toner full / Pre toner near-end The toner end sensor monitors the sub hopper but not the toner cartridge. The threshold for consecutive “Toner run out” detections is 41 (SP3120-001) | |
4. Toner End | Prerequisite: Toner Near-end Either 400 sheets was printed since toner near-end, or the estimated pixel count indicates toner end, whichever comes first. |
