| TITLE: SOLUTION TO LNC01 PRINT QUALITY PROBLEM.
SYMPTOM:
A dragged image on the trailing edge of the paper from approximately
11mm in front of the trailing edge. On subsequent sheets coloured lines
approximately 50mm apart at a right angle to the direction of paper
movement.
CAUSE:
This has only been seen so far on machines running with a paper weight of
90gsm+. It is caused by the paper being fed onto the transfer drum the
wrong way up. This causes the trailing edge to break away from the
transfer drum and hit the attraction roller assembly.
QUICK CHECK:
Open the transfer drum top access cover. As the paper rotates past the
separation assembly you can see that the trailing edge has lifted off
the transfer drum.
SOLUTION:
Ensure that the peak of the greatest curve of the paper is up when
loading paper into the cassette unit and down when loading the side feed
tray. This ensures that the natural curl of the paper follows the curve
of the transfer drum surface.
The natural curl of the paper can be determined by balancing a sheet of
paper with one finger from each hand positioned half way down each long
edge of the paper. Then flip the paper over, and repeat the experiment,
to determine the orientation with the most natural curl.

=====================================================================
PROBLEM:
What are the interchangeable parts and compatibility issues of a V1
(LSR 2000) versus a V2 (LSR 2000+)?
The V1 and V2 pieces and parts consist of (1) controller, (2) proms,
(3) memory, (4) hard disk drive, (5) and SW; as well as print engine
user documentation and disks. The interchangeability & compatibility
of these parts are described below.
RESOLUTION:
I. Summary

+ V1 proms
B. V2 HW includes:
+ V2 controller (29-33363-01)
+ 341Mb HDD (29-33364-01)
+ 16 or 32Mb as 4 - 4Mb or 4 - 8Mb SIMM's
+ V2 proms
C. V1 vs V2 valid product configuration types:
- V1 printers (V1 HW and V1 SW) require

+ at least 32 Mb (48Mb max)

+ V1 docs & disks (29-33057-01 English)
- V2 printers require
+ V2 SW - with user disk (29-33362-01)
+ 514 or 341 Mb HDD
+ V1 or V2 controllers *
+ 16 Mb or 32 Mb (48Mb max) *
+ V2 proms *
+ V2 docs (EK-LCPLE-DK English)
* NOTE: v2.x printer software with V1 HW with V1 EPROM dated
2/21/96 can NOT use memory configuration of 32 Mb
using 8 - 4 Mb SIMMs (this is not standard configuration)

as well as older service plans
1) Controller PCB's:
- see other sections in this blitz for compatibility
2) PROMS:
There are 2 types of proms (which are socketed):
a. EEPROM (Non-volatile Memory) contains/retains setup information
and the Ethernet address:
This chip should be kept ONLY with it's V1 or V2 PCB.
This is noted on the controller PCB by U11
b. EPROM contains the boot and POST (Power on self test) code.
This chip should be kept ONLY with it's V1 or V2 PCB.
This is noted on the controller PCB by U5
NOTE: v2.x printer software with V1 HW with V1 EPROM dated
2/21/96 can NOT use memory configuration of 32 Mb
using 8 - 4 Mb SIMMs (this is not standard configuration)
3) Memory - the SIMM TYPES for V1 and V2 products are the same
- there are 2 models for V2 and 1 for V1
a. V1 32 Mb model = 4 - 8Mb simms
b. V2 32 Mb model = 4 - 8Mb simms
c. V2 16 Mb model = 4 - 4Mb simms
NOTE: v2.x printer software with V1 HW with V1 EPROM dated
2/21/96 can NOT use memory configuration of 32 Mb
using 8 - 4 Mb SIMMs (this is not standard configuration)
4) V1 514 Mbyte Hard Disk Drive (HDD) versus V2 341 Mbyte HDD:
a. History
- V1 SW has a performance problem (runs slower) using
smaller 341 so 514 was used
- 514M HDD vendor Quantum discontinued product
- V2 SW improved performance so 314 is as good as
514 except for size (see position statement)
b. If a 514M HDD is not available in stock it should be replaced
with a 341 and V2 SW should be loaded onto the V1 HW for
remedial HDD action; note: this requires LNC1X-CF (see below).
c. Position statement:
In developing the V1.0 LSR2000, the Digital product teams original
requirements plan called for a 340 MB hard disk drive. In testing the
LSR2000, we discovered that the 341MB hard drive did not provide the
appropriate level of print performance due to inefficiencies in the
system software. To overcome this problem, a more expensive 514 MB
hard disk drive was incorporated into the LSR2000.
In September of 1996, the Version 2.01 system software was released
and the LSR2000+ hard disk drive was reverted back to the originally
planned 341 MB HDD. Due to the improvements made in the V2.01 system
software, the 341 MB HDD now provides the same level of performance
as that available with the 514 MB HDD. The only difference between
the two versions is the overall number of jobs that can be stored on
the internal drive, otherwise print performance remains unchanged.
During the version 2.01 LSR2000+ release, all marketing collaterals
delivered to the geographies noted the 341 MB HDD size. Realizing
that this change may not be well received by customers, the product
team has explored many options to obtain a larger hard disk drive.
In our search we have discovered the supplier (Quantum) discontinued
the line of hard drives utilized in the LSR2000 and only had enough
341 MB drives to cover Digital's sales requirements. Given that the
current controller design will only accommodate the discontinued
Quantum hard drive, a new controller board design is required
to obtain a drive larger than the present 341 MB.
At this time, Digital has no plans for re-designing the LSR2000+
controller board due to the cost implications. If we were to move
ahead with such a proposal, the cost of doing so would heavily burden
the product costs and dramatically increase the manufacturers list
price.
5) Loading SW:
a. HDD failure - verify by extended diagnostics check
- A V2 printer should be reinstalled to V2 via attached
CD-ROM; with 341Mb spare
- A V1 printer should be reinstalled to V1 via attached
CD-ROM;
- A V1 printer can be upgraded to V2 via attached CD-ROM,
but LNC1X-CF ($159) is required. This kit
includes new CDs, documentation and labels.
Utilities and drivers must be upgraded on
user's Macintosh and Windows PCs.
b. SW upgrade: (All V1 & V2s can be loaded with V2 level SW)
- A V1 printer can only be upgraded via attached CD-ROM.
Kit LNC1X-CF is required.
- A V2 printer can be upgraded via attached CD-ROM,
or parallel cable or network via Macintosh
or Windows PC. Kit is available from LNC1X-CH
or Web site (http://www.printers.digital.com)
