Ricoh D293 DSm2640

Symptom:

The image density decreases with continuous printing, especially in solid image areas (though it is within specification).
• This does not occur in text areas.

Cause:

This may occur due to the condition of the developer, and also occurs more easily when repeat prints are made from the same original.

Solution:

Change the following SP modes as shown.

• SP3-629-001 (Vc Vsp): Set to 530
• SP3-629-101 (Vb Vsp): Set to 330

Note:

• This will increase the amount of toner used to develop the image.
• As a side effect, this will shorten the yield of the toner bottle.
