[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 182 Deterioration of photo sensitivity due to deterioration of OPC drum is corrected by adjusting the laser beam power according to the OPC drum rotating time (operation time) to maintain the correct density print. LASER BEAM POWER CORRECTION 1 [mW] Laser beam power 0.2mW (max) (AR-280/285/335) 0.12mW (max) (AR-250/281/286/287/336/337) 0.16mW (max) (AR-405/407/501/505/507) Laser beam power correction value( LPc1)
Page 183 2) Connect the three points of three toner patch density points with strait lines, and check that it reaches the reference density. If the above condition is satisfied, obtain the correction developing bias voltage (Vdbc(n)) for the reference density by linear approximation. The reference density: 38 (set with SIM 44-4) for AR-280/285/335/405/407 58 (set with SIM 44-15) for AR-250/281/286/287/336/337 36 (set with SIM 44-4) for AR-501/505/507 3) Calculate the developing bias correction voltage (v Vdbc(n)).
