Product FAQs

. How often should I clean the filter?
To ensure maximum cooling capacity and efficiency you should keep the filter clean. During peak usage times the filter should be inspected on a weekly basis to make sure that it is not clogged with dust.

. Is the air conditioner easy to install?
On our models greater than 8,000 BTU/hr. the units are manufactured with a slide out chassis to make installation a breeze. The cabinet is set in place without the chasis in it, and then when it is secured you slide the cooling unit into the cabinet.

. What does EER mean?
The EER, or Energy-Efficiency Rating, measures the air conditioner's energy consumption and efficiency. A high EER rating means less energy is being consumed.

. What size air conditioner do I need?
The cooling capacity of an air conditioner is measured in British Thermal Units (BTU), and the capacity you require depends mostly on the size of the room you need to cool. If you buy an air conditioner that is to small for the room it will not cool adequately. If you buy one that is too large, the air conditioner will cool the room before it dehumidifies and this can leave you feeling clammy. For larger areas, sometimes two smaller units are more efficient than 1 large unit. You can use the following chart as a rough guide, your Sharp dealer will have additional details.

. The tuning up and down buttons on my remote control do not work.
These buttons will only work if you have already preset the stations into the unit's memory. Please see "Preset Tuning" located in the "Tuner Operation" section of your instruction manual.

. What can I do if my audio system is malfunctioning and not operating correctly?
We suggest unplugging the unit and then plugging it back into the wall outlet. If the problem still exists, we suggest clearing the memory by resetting the unit.

. Print quality is poor when I receive a fax, print a report or make a copy, what can I do?
Your plain paper fax machine uses a thermal wax ribbon to print with. Like any other printer, paper is very important. For the best possible quality, Sharp recommends using laser quality paper in your fax machine. This paper is produced with a very smooth finish for laser printers and offers thermal wax printers the same quality level. Although copier paper will work, it sometimes tends to offer lighter print quality. You may purchase laser quality paper at any office supply retailer or dealer.

. Should I buy a laser machine or a thermal transfer machine?
Both units use plain paper to print faxes and make copies. Laser machines use toner and a drum like a laser printer. Some laser fax machines can be used also as a laser printer.

. Smudges and dirt appears on my copies, how can I correct this?
Smudges and dirt can be caused by the following: Original table or original cover is dirty. Clean it regularly. See your manual for details. Original is smudged or blotchy. Use a clean original

. The Power save indicator is on, what does this mean?
Two possible causes are: he copier is in preheat mode, press any key to cancel the preheat mode. The copier is in auto power shut-off mode. Press the print key to cancel auto power shut-off

. What are the possible causes of paper misfeeds?
Paper misfeeds can be caused by the following problems: Using non-standard paper. Use standard paper and feed special papers through the manual bypass. See your operation manual for details. Damp or curled paper can cause a misfeed. Store copy paper flat in the wrapper in a dry location. Are there pieces of paper inside the copier? Remove all pieces of misfeed paper. Paper guides in the paper tray need to be set correctly. Set guides properly depending on paper size being used. Do not overfill paper tray. Remove excess paper from the paper tray.

. What is the difference between thermal and thermal transfer?
Thermal fax machines use thermal paper rolls. Faxes and copies are printed onto the paper using heat. Thermal Transfer technology uses plain paper and a film ribbion to print faxes and copies onto the paper.

. Why do my copies have stripes on them?
The transfer charger should be cleaned. See your operation manuals for details.

. Why do my images rub off the copy easily?
The paper being used could be too heavy. Use paper within specified range. The paper being used could also be damp. Replace any damp paper with dry copy paper. If the copier is not going to be used for a length of time, remove the paper from the paper tray and store it in its wrapper in a dry location.

.  Why is my copier making blank copies?
Make sure the original is face down on the platen (glass copy surface).

. Will my fax machine work with my answering machine?
Yes. Most of our units allow an answering machine to work with it. When a fax is coming in, the fax monitors the call to see if its another fax machine. If it is, it will automatically answer it.
