Abstract
The disclosure relates to a scantling unit (20) comprising an interlocking assembly (45). The interlocking assembly (45) comprises; an interlock arm (40) pivotably connected to a scanner base of the scanning unit (20) and movable between a locked position and an unlocked position; and a biasing mechanism, for biasing the interlock arm toward the locked position, A combo gear (31) of the scanning unit (20) is locked by the interlocking assembly (45), thereby being prevented from, rotating, before a scan bar driver gear (26) of the scanning unit (20) engages with the combo gear (31) of the scanning unit (20).
Claims16
A scanning unit (20) comprising an interlocking assembly (45), the interlocking assembly (45) comprising:
- an interlock arm (40) pivotably connected to a scanner base of the scanning unit (20) and movable between a locked position and an unlocked position;
- and
- a biasing mechanism for biasing the interlock arm toward the locked position,
- wherein a combo gear (31) of the scanning unit (20) is locked by the interlocking assembly (45), thereby being prevented from rotating, before a scan bar driver gear (26) of the scanning unit (20) engages with the combo gear (31) of the scanning unit (20).
A scanning unit (20) for an image forming apparatus (1), comprising:
- a scanner base,
- a scan bar driver gear (26),
- a combo gear (31), and
- an interlocking assembly (45) comprising;
- an interlock arm (40) pivotably connected to the scanner base and movable between a locked position and an unlocked position;
- and
- a biasing mechanism, for biasing the interlock arm toward the locked position,
- wherein the combo gear (31) is locked by the interlocking assembly (45), thereby being prevented from rotating, before the scan bar driver gear (26) engages with the combo gear (31).
