COPIER : SF-2014

1. CHANGES TO IC INSIDE MAIN PWB

2. INSUFFICIENT RECOVERY OF LEADING ROLLER AND ACTUATOR INSIDE P APE R FEEDING UNIT

3. SPACER SETTING FOR ADJUSTING HORIZONTALLY

1. Changes to IC inside main PWB

1.Model name: SF-2014, 2114, 2214

2.General: We have changed the IC using in the main PWB to the mask PWB. There is no change

in its program.

No. : SP-1847

3.Action: From the first unit of October 1994 production

2. Insufficient recovery of leading roller and actuator inside paper feeding unit

1.Model name: SF-2014, 2114, 2214

2.General: The cassette could not be pulled out because the leading roller inside the paper feeding

unit remains down on rare occasion. The actuator recovered insufficiently on rare occasion because of unbalanced load on the springs. (We had set them in the item 9 of the T/R SP-1842.)

3.Description: We have changed coiling angle of the roller release arm spring 250 (MSPRC2201FCZZ), 18 -28 and 52 -16.

90°

Fold this point

2.General: We have set the rubber spacer to be more convinient to adjust the copier horizontally. Put these spacers under the machine in case of fixing it with inclining and adjust it by taking current measures. These spacers can be used in other machines.
