Introduction
Warning
Note
This chapter introduces you to the M1700A PageWriter XLi,
M1701A PageWriter XLs, and M1702A PageWriter XLe cardiographs
and lists their technical specifications.
These cardiographs are only to be serviced by qualified personnel.
Safe and effective use of medical instrumentation requires periodic
inspection and preventive maintenance. Perform the preventive
maintenance procedures in Chapter 4 of this manual at required
intervals to ensure satisfactory instrument performance.
The cardiographs use a thermal printhead to record waveforms and
label the ECG report. The paper supplied with the cardiographs is a
special thermal paper designed specifically to work with the thermal
printhead and the photo detector used to advance the paper.
The cardiograph’s clisk drive (M1700A & M1701A only) is a critical
part. Disks of substandard quality can damage the clrive or destroy
patient clata.
Hewlett-Packarcl guarantees the performance of the cardiographs only
when used with paper and disks that meet or exceed Hewlett-Packard
specifications.
PageWriter XL
Cardiographs
The M1700A PageWriter XLi is Hewlett-Packard’s full-featured,
interpretive cardiograph. The M1701A PageWriter XLs is the
standard, non-interpretive cardiograph. The M1702A PageWriter
XLe is the basic, non-interpretive cardiograph. Each cardiograph
uses a patient module, which is a remote “front end” that acquires
and digitizes clata. The M1700A and M1701A patient modules
feature a start button ant1 an LCD display that indicates signal
quality. The M1702A patient module does not feature a display
or start button. The cardiograph main unit has the user controls,
the disk drive (M1700A and M1701A only), the printer, and all the
processing circuitry. All models use the same enclosure, except when
the h41700A is equipped with preview display. The models fit onto
the M1705A cart clesigneclfor these carcliographs. Figure l-1 shows
the M1700A with preview display mounted on the cart.
Introduction l-l

Figure l-l. M1700A PageWriter XLi Cardiograph with Preview Display.
The PageWriter XL family of cardiographs can print ECGs in Auto
and Manual formats for different clinical tests or applications. Both
cardiographs print all traces with a continuous feed, high-resolution,
digital array printer. This produces electrocardiograms on standard
page lengths that require no cutting or mounting. Records are clearly
annotated with ECG data and patient information. The M1700A
also labels records with automatic ECG measurements and ECG
interpretation for both adult and pediatric patients.
The Ml700 ant1M1701A cardiographs use flexible disks for storing
ECGs. Exact ECG copies can be made at the bedside or Iater. Each
ECG is automatically logged and can be automatically stored by the
cardiograph. A list of all stored ECGs can be printed, facilitating
administrative reporting and billing. Typically, 50-150 ECGS can
be stored per flexible disk, although the actual quantity depends on
usage.
From a service standpoint, the PageWriter XL cardiographs are
similar except for five major hardware differences:
H The h41700A preview display allows you to view the ECG prior to
recording.
n The M1700A CPU assembly has extra nlenlory to accommodate
the measurement and interpretation software, but uses the same
ROM as the M1701A.
n Each PageWriter has a unique CPU asscnibly.
1-2 Introduction

n The M1700A and M1701A load software from, and store ECGs to,
the disk drive. The M1702A software is in ROM, and does not
store ECGs.
n The M1700A and M1701A patient modules feature a display that
indicates signal quality and a start button. The M1702A patient
module does not offer these features.
All other model differences are found in the cardiograph’s software.
The M1700A and M1701A software is installed in the cardiograph
from flexible disk, while the M1702A software is installed from ROM.
After installation, the software is stored in dynamic RAM (DRAM).
Re-installation is required only when a user desires a different
configuration, or if DRAM loses its contents due to a low battery.
The PageWriter XL family of cardiographs is designed for long-term
reliability. The modular clesign makes extensive use of VLSI and
gate array technology, resulting in a minimum number of major
subassemblies. The modular approach means less down-time for the
user, since replacing subassemblies allows quicker field repairs. The -
extended self-test efficiently identifies faulty subassemblies, further
speeding the repair process.
Note t?
:’
As of February 1992, all new PageWriter XL cardiographs are
manufactured to a revised mechanical design specification. All units
having a serial number prefix of 3208A or later conform to this
revised specification. This manual describes all specific differences.
The following paragraphs describe some of the significant options
available for the PageWriter XL cardiographs.
M1705A Cart
The M1705A Cart provides mobility for the PageWriter XL family
of cardiographs. The large wheels make the cart easy to move, yet
steady when in use. Slots in the cardiograph’s feet and a thumbscrew
secure the cardiograph to the cart rails, The tray directly below the
cardiograph provides storage for acquired ECGs, the user’s guide,
and several flexible disks. The tray also has molded fittings that
accommodate the modem in the M170GA/B Telecommunications
Package. Storage for the power cable is built in, and other built-in
cable retainers hold the patient clata cable out of the way. Two
compartmented trays provide storage for the patient module,
spare patient electrodes and leaclwires, additional thermal paper,
consumable supplies, and miscellaneous items. An optional paper
management tray is also available for the M1705A.
