Title: Automatic density adjusting mechanism for copying machine
Inventor: SUZUKI SEIICHI
IPC: G03G15/06
Filed: 1988-07-26
Abstract: PURPOSE:To correct EE adjustment by means of a simple circuit configuration without adding an extra component by storing correction data, and automatically adjusting density based on the correction data. CONSTITUTION:Through a combination of predetermined keys on an operation panel, an EE correction mode is set. By this time, a control circuit 30 detects the resistance value of a variable resistance 41; that is, the resistance value of the variable resistance 41 is inputted as correction data. The correction data is displayed on a display part 43. An operator operates the resistance 41 by ascertaining the display. After the correction data is inputted, the correction data is determined by depressing an EE selecting switch again. This correction data is stored in a memory 42. After this, EE is performed, centering around a bias voltage which is shifted by the correction data. This eliminates base fog caused by the deterioration of a photosensitive drum.
