It appears that some machines have a sub-image format at higher resolutions.
You could try this:

Change line 1150 of pixma_mp150.x to:

   if (s->cfg->pid == MP600_PID || s->cfg->pid == MP600R_PID || 
s->cfg->pid == XK90_PID)

...and add this around line 1190:

                   || s->cfg->pid == XK90_PID


And let me know if this fixes the issue.

Cheers,
Ralph
