first find the PID for your device. E.g for my mx980 lsusb shows

Bus 001 Device 009: ID 04a9:172d Canon, Inc., so my PID is 172d.
Add an appropriate line at the top of pixma_mp150.c at the top (right
after the MX870.

Add an s->cfg->spid == MX885 to the if statement around line 1226 (where
the is a check for MX_870_PID

Replicate the MX870 line around line 1643 and change the MX870 refernces
as appropriate.

If the scanners are really close in capabilities and command set that
should do the job.
Check the capabilities (CCD vs CIS sensor) to make sure.
