AR-505 [10] OPERATIONAL DESCRIPTION Correcting operation in the image forming section (Process correction operation) 1. Outline and purpose The operations of the image forming section are corrected in order to maintain stable and high-quality print even when changes occur in the temperature, humidity, consumable parts characteristics, engine conditions, or other environmental conditions.
Page 167 AR-505 B. Details of operations (1) OPC drum marking sensor sensitivity adjustment (Calibration) and marking detection a. Outline and purpose The sensor sensitivity is adjusted to allow correct detection of the OPC drum marking. b. Details (Calibration) The sensor LED drive voltage (current) is changed, and when the sensor output voltage reaches the specified level, the sensor LED drive current control value is stored.
Page 168 AR-505 (5) Developing bias voltage correction a. Outline and purpose Deterioration of developer due to changes in the environmental conditions. To solve the above problem, the developing bias voltage is changed according to the situation to maintain the proper density print and prevent against background copy.
Page 169 AR-505 (6) Main charger grid voltage correction 2 (9) Toner concentration correction B a. Outline and purpose a. Outline and purpose When the developing bias voltage is changed, the main charger grid Developer shows an inclination of overtoning with age. To prevent voltage correction 2 is performed to maintain the relation between the against this, the reference toner concentration control level is developing bias voltage and the main charger grid voltage at con-...

Page 173 AR-505 The document length is detected by counting the number of pulses of the paper feed motor (AMOT) and the transport motor (FMOT) during the time interval from when the paper feed motor (AMOT) starts rotation, that is, the resist roller starts rotation, and a document is fed from the paper feed section to the paper transport section to when the post-separation sensor (SPS) detects the rear edge of the document.
Page 174 CAUTION FOR BATTERY REPLACEMENT (Danish) ADVARSEL ! Lithiumbatteri – Eksplosionsfare ved fejlagtig håndtering. Udskiftning må kun ske med batteri af samme fabrikat og type. Levér det brugte batteri tilbage til leverandoren. (English) Caution ! Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type recommended by the manufacturer.
