Canon projector LV7585 User Manual

							
61

This projector uses a high-pressure lamp which must be handled carefully and properly. 
Improper handling may result in accidents, injury, or create a fire hazard.
● Lamp  lifetime  may  differ  from  lamp  to  lamp  and  according  to  the  environment  of  use. There  is  no 
guarantee  of  the  same  lifetime  for  each  lamp.  Some  lamps  may  fail  or  terminate  their  lifetime  in  a 
shorter period of time than other similar lamps.
● If  the  projector  indicates  that  the  lamp  should  be  replaced,  i.e.,  if  the  LAMP  REPLACE  indicator  lights 
up,  replace  the  lamp  with  a  new  one  IMMEDIATELY  after  the  projector  has  cooled  down.  (Follow 
carefully the instructions in the Lamp Replacement section of this manual.) Continuous use of the lamp 
with the LAMP REPLACE indicator lighted may increase the risk of lamp explosion.  
● Lamp  may  explode  as  a  result  of  vibration,  shock  or  degradation  as  a  result  of  hours  of  use  as  its 
lifetime  draws  to  an  end.  Risk  of  explosion  may  differ  according  to  the  environment  or  conditions  in 
which the projector and lamp are being used.
IF A LAMP EXPLODES, THE FOLLOWING SAFET y PRECAUTIONS SHOULD BE TAKEN .
If  a  lamp  explodes,  disconnect  the  projector’s  AC  plug  from  the  AC  outlet  immediately.  Contact  an 
authorized  service  station  for  a  checkup  of  the  unit  and  replacement  of  the  lamp.  Additionally,  check 
carefully to ensure that there are no broken shards or pieces of glass around the projector or coming out 
from  the  cooling  air  circulation  holes.  Any  broken  shards  found  should  be  cleaned  up  carefully.  No  one 
should  check  the  inside  of  the  projector  except  those  who  are  authorized  trained  technicians  and  who 
are familiar with projector service. Inappropriate attempts to service the unit by anyone, especially those 
who are not appropriately trained to do so, may result in an accident or injury caused by pieces of broken 
glass.
          LAMP HANDLING PRECAUTIONS
Maintenance and Care

Unplug the AC power cord before cleaning.
Gently wipe the projection lens with a cleaning cloth that 
contains a small amount of non-abrasive camera lens 
cleaner, or use a lens cleaning paper or commercially 
available air blower to clean the lens. 
Avoid using an excessive amount of cleaner. Abrasive 
cleaners, solvents, or other harsh chemicals might scratch 
the surface of the lens.
Cleaning the Projector Cabinet
Unplug the AC power cord before cleaning.
Gently wipe the projector body with a soft dry cleaning 
cloth. When the cabinet is heavily soiled, use a small amount 
of mild detergent and finish with a soft dry cleaning cloth. 
Avoid using an excessive amount of cleaner. Abrasive 
cleaners, solvents, or other harsh chemicals might scratch 
the surface of the cabinet.
When the projector is not in use, put the projector in 
an appropriate carrying case to protect it from dust and 
scratches.

The WARNING indicators show the state of the function which protects the projector. Check the state of the 
WARNING indicators and the POWER indicator to take proper maintenance. 
Warning Indicators
The projector is shut down and the WARNING TEMP. 
indicator is blinking red.
When the temperature inside the projector reaches a 
certain level, the projector will be automatically shut down 
to protect the inside of the projector. The LAMP indicator 
turns red and the WARNING TEMP indicator blinks while 
the projector is being cooled down. When the projector has 
cooled down enough (to its normal operating temperature), 
it can be turned on again by pressing the POWER button.
✔Note:
	•	 The	WARNING	 TEMP.	indicator	continues	to	blink	even	after	the	
temperature	inside	the	projector	returns	to	normal.	 When	the	
projector	is	turned	on	again,	the	 WARNING	TEMP.	indicator	stops	
blinking.	
Then check the matters below:
–   Did you provide appropriate space for the projector to be 
ventilated? Check the installing condition to see if the air 
vents of the projector are not blocked.
–   Has the projector been installed near an Air-Conditioning/ 
Heating Duct or Vent? Move the installation of the 
projector away from the duct or vent.
–   Is the filter clean? Replace the filter with a new one.
The projector is shut down; and the LAMP indicator is 
lighting and other four indicators are blinking.
When the projector detects an abnormal condition, it will 
be automatically shut down to protect the inside of the 
projector and the LAMP indicator lights on and other four 
indicators blink. In this case, unplug the AC power cord and 
plug it, and then turn on the projector once again to verify 
operation. If the projector cannot be turned on and these 
indicators are still lighting and blinking, unplug the AC power 
cord and contact the service station.
CAUTION
DO NOT LEAVE THE PROJECTOR WITH THE 
AC POWER CORD CONNECTED UNDER AN 
ABNORMAL CONDITION. IT MAY RESULT IN FIRE 
OR ELECTRIC SHOCK.

Troubleshooting
Before calling your dealer or service center for assistance, check the items below once again.
1. Make sure you have properly connected the projector to peripheral equipment as described \
on pages 20–21.
2.  Check the cable connection. Make sure that all computers, video equipment, and power cords are properly 
connected.
3.  Make sure that all power is switched on.
4.  If the projector still does not produce an image, restart your computer.
5.  If an image still does not appear, disconnect the projector from your computer and check your computer 
monitor’s display. A problem may be noticed with your graphics controller rather than with the projector. 
(When you reconnect the projector, be sure to turn the computer and monitor off before you turn on the 
projector. Turn on equipment in the order of the projector and computer.)
6.  If a problem still persists, check the following solutions.
No power  .● Plug the power cord of the projector into the AC outlet.
● Wait  until  the  POWER  indicator  stops  blinking  to  turn  on  the  projector  again.  (See  page 
23)
●  Check  the  WARNING TEMP.  indicator.  If  the  WARNING TEMP.  indicator  is  blinking,  the 
projector cannot be turned on. (See page 63.)
● Check the projection lamp. (See page 59.)
● Unlock the Key lock function for the projector.  (See page 53)
● See if the filter cartridge is inserted. (See page 57)
Image is out of focus .● Adjust the focus of the projector.
● Make sure the projection screen is at least 4.6’ (1.4 m) away from the projector.
● Check the projection lens to see if it needs cleaning.
NOTE:   Moving  the  projector  from  a  cool  to  a  warm  place  may  result  in  moisture 
condensation  on  the  projection  lens.  If  this  happens,  leave  the  projector  off  and 
wait until condensation evaporates.

● It takes about 30 seconds to display an image after turning on the projector.
● See if the selected system is corresponding with your computer or video equipment.
● Make sure the temperature is not out of specified operating temperature (41˚F–104˚F
    [5˚C–40˚C]).
