| N | PF Release Sensor (PF Driven RLS Sensor) | Check if the PF driven roller is Nip | When feeding paper, when discharging paper. |
| Through beam | OFF | |
| O | Sub PF Release Sensor (Middle Driven RLS Sensor) | Check if the Sub PF driven roller is Nip | When feeding paper, when discharging paper. | Through beam | OFF | ||
| P | Sub PF Encoder | The scale of the sub PF roller is read and the position is confirmed. | When the power is ON, when feeding, and discharging paper. | Through beam | OFF | ||
| Q | PF Encoder | The scale of the sub PF roller is read and the position is confirmed. | When the power is ON, when feeding, and discharging paper. | Through beam | OFF | ||
| R | 1st / 2nd Release Motor |
| If being not at the origin when the power is turned on, look for it (PF driven sensor) (PF driven RLS sensor) Sub PF driven sensor. (It does not move if it recognizes that it is at the origin with an intermediate driven RLS sensor), when feeding paper, when printing. |
| Through beam | OFF | |
| S | Paper Eject Star Wheel Roller Motor Unit Release encoder |
| Most of them are used at the time of printing except for film type (media whose surface is easily scratched: photo glossy paper is used). |
