Hi,
If your printer is connected in the Network and you are able to print fine than there is no communication Error.
In htan case if you are not able to scan then you need to upgrade the firmware of the printer and install it and i m sure your printer wiill scan scanning on the Network.
Mentioned below is the link to download the latest firmware of the printer.

However before you start sending firmware to the printer you need to make sure that printer driver is installed on the PC.

Thanks and Regards

To perform a cold reset
1 Turn the MFP off and then on.
2 When the memory count appears on the control-panel display, press and hold 6 until all three
LEDs flash once and then stay on. This might take up to 20 seconds.
3 Press 3 four times until COLD RESET appears on the control-panel display.
4 Press 6 one time. The MFP continues its initialization sequence.

This is caused by a dirty laser unit.

It is possible to clean the lenses and mirrors (with care not to scratch the surface silvered mirros AND not to disturb eany of the optical components)

There's quite a bit of dismantling to do to get to the laser unit, but if you work methodically (and remember to double check everything when you are 'rebuilding' the printer) it is certainly possible.

This is a common problem and also appens with HP Color Laserjet 1600, 2600, 2605, CM1017, and Canon LBP5000.
