-
+However, patches are available that support most of the CIS type scanners.
+Check out the homepage of Eddy De Greef for these patches (see the
+.B SEE ALSO
+section). 
+.PP
+These patches have been reported to work on the Mustek 600CP, 1200CP, 
+and 1200CP+ models, and various OEM versions (LifeTec/Medion 9350, 9351,
+9850, 9851, 9858, 9890, and 9891; Trust Easy Connect 9600 plus; 
+Targa Funline TS12EP).
+.PP
+When installing these patches, 3 additional options are available in the 
+.B mustek_pp.conf 
+configuration file (see 
+.BR CONFIGURATION ): 
+.BR cis600 ,
+.BR cis1200 ,
+.BR cis1200+ .
+.PP
+These options select the 600CP, 1200CP, or 1200CP+ version of the driver. 
+One of them must be set.
+.PP
+The 600CP has a maximum resolution of 300x600 DPI, whereas the 1200CP
+and 1200CP+ have a maximum resolution of 600x1200 DPI. The option must
+match your scanner. If unsure, check the manual or the box.
+.br
+.B Choosing the wrong option could damage your scanner!
+.B Especially, using the 1200CP settings on a 600CP can be harmful.
+.B If the scanner starts making a loud noice, turn it off immediately !!!
+.PP
+The 
+.B cis...
+options cannot be combined with the 
+.BR use600
+option.
+.PP
+Currently, when installing the CIS patches, support for CCD type scanners is
+disabled. In future versions of the
+.B sane-mustek_pp 
+backend, the CIS patches will be integrated and support for both types
+of scanners will co-exist.
