        PSF PTFS FOR 3900 AFCCU MICROCODE UPGRADE & INFOPRINT 4000
 
PTFs are required to PSF/MVS 2.2, PSF/MVS 2.1.x, and PSF/VSE 2.2 when
upgrading 3900 AFCCU microcode to version 8.4 or higher, and when
upgrading a 3900 AFCCU printer to an InfoPrint 4000 printer (which
requires level 8.4 or higher microcode).
 
New function in 8.4 level microcode changed a response field checked by
PSF/MVS and PSF/VSE.  This unexpected response causes PSF without
maintenance to ABEND (024, RC 023) when the printer is initialized. The
maintenance is provided with PSF/MVS 2.2 APAR OW18369, PSF/MVS 2.1.x
APAR OW26041, and PSF/VSE 2.2 APAR DY44429.  PSFs on other platforms do
not verify this field, so are not affected by the changed response.
 
An upgrade from a 3900 AFCCU printer to an InfoPrint 4000 may also call
for a change to IOCP.  If the 3900 printer is defined to MVS as device
type "AFP1", no change is needed.  However if it is defined as device
type "3900" then after upgrade to an InfoPrint 4000, a warning message
will be issued every time the printer is varied online.  This will not
prevent printing, but will become annoying.  Eventually you will want to
change the device type to "AFP1" or to "4000".  PSF/MVS APAR OW22965 is
needed to define the printer to HCD as "4000".
 
There are additional APARs as well that fix specific problems your
customer may encounter, so the best advice is to get your 3900 AFCCU and
InfoPrint 4000 customers up to the latest PSF level of maintenance.  And
ALWAYS CHECK THE PSP BUCKETS when planning for the installation or
upgrade of a printer.
