Indicator display Projector status  Procedure
Off No problem
Flashing Red (cycles of 2) Temperature problem The temperature protector has been activated. If the room 
temperature is high, move the projector to a cool place. If the 
problem still persists, contact an Ricoh projector customer 
support center.
Lit Orange High surrounding temperature The surrounding temperature is high. Lower the room tem-
perature.
If the temperature protector is activated
If the projector’s internal temperature rises abnormally, the lamp turns off and the temperature indicator flashes (repeatedly in 
cycles of 2).
It may happen that the projector’s temperature protector is simultaneously activated and the projector’s power turns off.
If this happens, do the following:
- Unplug the power cord from the power outlet.
-  If using in a place where the surrounding temperature is high, move the projector to a different, cool place.
-  If there is dust in the ventilation holes, clean. (→ pages 171 and 174)
-  Wait as such about 1 hour for the projector’s internal temperature to lower.

Common Problems & Solutions
(→ “Power/Status/Lamp Indicator” on page 245.)
ProblemCheck These Items
Does not turn on
or shut down • 
Check that the power cord is plugged in and that the power button on the projector cabinet or the remote control 
is on. (→ pages 15, 16)
•  Ensure that the lamp cover is installed correctly. (→ page 177)
•  Check to see if the projector has overheated. If there is insufficient ventilation around the projector or if the room 
where you are presenting is particularly warm, move the projector to a cooler location.
•  Check to see if you continue to use the projector for another 100 hours after the lamp has reached the end of 
its life. If so, replace the lamp. After replacing the lamp, reset the lamp hours used. (→ page 129)
•  The lamp may fail to light. Wait a full minute and then turn on the power again.
•  Set [FAN MODE] to [HIGH ALTITUDE] when using the projector at altitudes approximately 5500 feet/1700 meters 
or higher. Using the projector at altitudes approximately 5500 feet/1700 meters or higher without setting to [HIGH 
ALTITUDE] can cause the projector to overheat and the projector could shut down. If this happens, wait a couple 
minutes and turn on the projector. (→ page 110)
  If you turn on the projector immediately after the lamp is turned off, the fans run without displaying an image 
for some time and then the projector will display the image. Wait for a moment.
Will turn off • Ensure that the [OFF TIMER], [AUTO POWER OFF] or [PROGRAM TIMER] is off. (→ page 113, 128)
No picture • Check if the appropriate input is selected. (→ page 18) If there is still no picture, press the INPUT button or one 
of the input buttons again.
•  Ensure your cables are connected properly.
•  Use menus to adjust the brightness and contrast. (→ page 89)
•  Ensure that the lens cover is open. (→ page 16)
•  Reset the settings or adjustments to factory preset levels using the [RESET] in the Menu. (→ page 129)
•  Enter your registered keyword if the Security function is enabled. (→ page 36)
•  If the HDMI input or the DisplayPort signal cannot be displayed, try the following.
- Reinstall your driver for the graphics card built in your computer, or use the updated driver.
  For reinstalling or updating your driver, refer to the user guide accompanied with your computer or graphics 
card, or contact the support center for your computer manufacturer.
  Install the updated driver or OS on your own responsibility.
  We are not liable for any trouble and failure caused by this installation.
•  Both the composite video signal from each input connector as the computer, BNC, and BNC (CV), and the S-\
video 
signal from the BNC (Y/C) Input connector are not output from HDMI OUT Connector of this projector.
•  Be sure to connect the projector and notebook PC while the projector is in standby mode and before turning on 
the power to the notebook PC.
  In most cases the output signal from the notebook PC is not turned on unless connected to the projector before 
being powered up.
* If the screen goes blank while using your remote control, it may be the result of the computer’s screen-saver 
or power management software.
• See also the page 249.
Picture suddenly 
becomes dark • 
Check if the projector is in the Forced ECO mode because of too high ambient temperature. If this is the case, 
lower the internal temperature of the projector by selecting [HIGH] for [FAN MODE]. (→ page 110)
Color tone or hue is 
unusual • 
Check if an appropriate color is selected in [WALL COLOR]. If so, select an appropriate option. (→ page 110)
•  Adjust [HUE] in [PICTURE]. (→ page 90)
Image isn’t square to 
the screen • 
Reposition the projector to improve its angle to the screen. (→ page 20)
•  Perform [GEOMETRIC CORRECTION] when the trapezoid is distorted. (→ page 100)
Picture is blurred • Adjust the focus. (→ page 22)
•  Reposition the projector to improve its angle to the screen. (→ page 20)
•   Ensure that the distance between the projector and screen is within the adjustment range of the lens.  
(→ page 233)
•  Has the lens been shifted by an amount exceeding the guaranteed range? (→ page 236)
•  Condensation may form on the lens if the projector is cold, brought into a warm place and is then turned on. 
Should this happen, let the projector stand until there is no condensation on the lens.
Flicker appears on 
screen • 
Set [FAN MODE] to other than [HIGH ALTITUDE] mode when using the projector at altitudes approximately 5500 
feet/1700 meters or lower. Using the projector at altitudes less than approximately 5500 feet/1700 meters and 
setting to [HIGH ALTITUDE] can cause the lamp to overcool, causing the image to flicker. Switch [FAN MODE] to 
[AUTO]. (→ page 110)
Image is scrolling 
vertically, horizontally 
or both • 
Check the computer’s resolution and frequency. Make sure that the resolution you are trying to display is sup-
ported by the projector. (→ page 237)
•  Adjust the computer image manually with the Horizontal/Vertical in the [IMAGE OPTIONS]. (→ page 91)

If there is no picture, or the picture is not displayed correctly.
• Power on process for the projector and the PC.
  Be sure to connect the projector and notebook PC while the projector is in standby mode and before turning on the power to 
the notebook PC.
  In most cases the output signal from the notebook PC is not turned on unless connected to the projector before being powered 
up.
NOTE: You can check the horizontal frequency of the current signal in the projector’s menu under Information. If it reads “0kHz”, this means there is no signal being 
output from the computer. (→ page 132 or go to next step)
•  Enabling the computer’s external display.
  Displaying an image on the notebook PC’s screen does not necessarily mean it outputs a signal to the projector. When using 
a PC compatible laptop, a combination of function keys will enable/disab\
le the external display. Usually, the combination of 
the “Fn” key along with one of the 12 function keys gets the exter\
nal display to come on or off. For example, NEC laptops 
use Fn + F3, while Dell laptops use Fn + F8 key combinations to toggle t\
hrough external display selections.
•  Non-standard signal output from the computer
  If the output signal from a notebook PC is not an industry standard, the projected image may not be displayed correctly. Should 
this happen, deactivate the notebook PC’s LCD screen when the projector display is in use. Each notebook PC has a different 
way of deactivate/reactivate the local LCD screens as described in the previous step. Refer to your computer’s documentation 
for detailed information.
•  Image displayed is incorrect when using a Mac
  When using a Mac with the projector, set the DIPswitch of the Mac adapter (not supplied with the pr\
ojector) according to your 
resolution. After setting, restart your Mac for the changes to take affect.
  For setting display modes other than those supported by your Mac and the projector, changing the DIP switch on a Mac 
adapter may bounce an image slightly or may display nothing. Should this\
 happen, set the DIP switch to the 13" fixed mode 
and then restart your Mac. After that, restore the DIP switches to a displayable mode and then restart the Mac again.
NOTE: A Video Adapter cable manufactured by Apple Computer is needed for a MacBook which does not have a mini D-Sub 15-pin connector.
•  Mirroring on a MacBook
*  When using the projector with a MacBook, output may not be set to 1024 × 768 unless “\
mirroring” is off on your MacBook. 
Refer to owner’s manual supplied with your Mac computer for mirroring.
•  Folders or icons are hidden on the Mac screen
  Folders or icons may not be seen on the screen. Should this happen, select [View] → [Arrange] from the Apple menu and 
arrange icons.
