Overview

This chapter provides an overview of the daily, weekly, and monthly routines that you
should perform for proper maintenance of the HP Indigo press 3050.
The following procedures are guidelines to performing press maintenance. All procedures
must be performed in accordance with the full procedures provided in the maintenance
sections of this guide.

Practical tips before performing maintenance routines

Before you perform any procedure, you should place an absorbing paper on the substrate
to protect it from humidity.
WARNING! If you have to disconnect or reconnect a cable during a maintenance procedure, turn off the
press main power supply. Lock and isolate the main circuit breaker in the Off position to avoid
inadvertent re-connection.
IPA contamination
The press inks are highly sensitive to IPA contamination. When you use IPA for cleaning,
always take special precautions not to contaminate the ink with even small amounts of
IPA. IPA can radically change the conductivity and electrical parameters of the ink. If you
suspect contamination, flush out the ink thoroughly and replace with new ink. Whenever
you use IPA, wait two to three minutes before you proceed to allow the IPA to completely
evaporate. If you cannot make a visual check, use your finger to feel for any dampness.
Water contamination
The inks used in the press are highly sensitive to water contamination. The press cooling
system uses water. Take special precautions not to contaminate the ink with even small
amounts of water. Water can radically change the conductivity and electrical parameters
of the ink. If you suspect contamination, flush out the ink thoroughly and replace it with
new ink.
PIP protection
The PIP is extremely sensitive to light. Make sure that you dim the lights in the operating
area. Take extra precautions when you open the input doors.
